            <title>[MC-409] Worlds not saving upon exit (single player)</title>
                <link>https://bugs.mojang.com/browse/MC-409</link>
                <project id="10400" key="MC">Minecraft: Java Edition</project>
                    <description>&lt;p&gt;After editing terrain in any world, upon saving and quitting the game doesn&apos;t show the &apos;saving level&apos; screen and instantly goes to the main screen. When I reload the world none of the terrain is saved, only my player&apos;s coordinates and inventory is saved.&lt;/p&gt;</description>

If so, please &lt;em&gt;update the affected versions&lt;/em&gt; in order to best aid Mojang ensuring bugs are still valid in the latest releases/pre-releases. If this has been done, we can reopen the issue.&lt;/p&gt;

&lt;p&gt;Keep in mind that the &quot;Resolved&quot;-Status on this ticket just means &quot;Answered&quot;, and that we are waiting for further information on whether this issue still exists or not. It will be reopened as soon as the requested information has been delivered.&lt;/p&gt;</comment>

I&apos;m on Windows 7, also played on Ubuntu and even Boardwalk on Android (port of PC minecraft to mobile), but it never happened, even with lag, freezes, crashes, etc. Also when I set the autosave time in Optifine to 30 minutes and the game crashed, it didn&apos;t happen (but I know that that doesn&apos;t count here). Does anyone have tips on how to reproduce this?&lt;br/&gt;
I have 7 of my 8GB RAM allocated to MC, but it also worked before and even on a sh*tty school computer (worse than phone) while hosting a server.&lt;/p&gt;</comment>

A: does your inventory save but not the world? My answer: Yes&lt;br/&gt;
B: does this occur on Windows 8? (Yes)&lt;br/&gt;
C: does this always occur or just sometimes (Sometimes)&lt;br/&gt;
D: does it occur in just one world or more than one (at least 2)&lt;br/&gt;
E: do all the block you placed since you logged in disappear or just the last 5-minutes or so? (only the last ones)&lt;br/&gt;
F: how do you fix the problem? (idk)&lt;br/&gt;
G: what 1.8.5-compatible versions of Minecraft fix this issue? (idk)&lt;/p&gt;

&lt;p&gt;For these conditions: confirmed.&lt;/p&gt;</comment>

When shutting down a server I&apos;ve noticed an error a couple of times with no corresponding crash-report generated. Once in the middle of saving the players, and once in the middle of saving chunks.&lt;/p&gt;

The problem being that changes from the last time I played were not saved even though it appeared to exit normally. As for memory settings, I have been tinkering with those recently, yet, it occurred when using the default settings as well. At this point I&apos;ve already deleted everything except my saves and launcher profiles and am keeping an eye on things to see if it occurs again.&lt;/p&gt;</comment>
                            <comment id="220161" author="kumasasa" created="Tue, 24 Feb 2015 08:22:05 +0100"  >&lt;p&gt;@&lt;a href=&quot;https://bugs.mojang.com/secure/ViewProfile.jspa?name=someone3x7&quot; class=&quot;user-hover&quot; rel=&quot;someone3x7&quot;&gt;someone3x7&lt;/a&gt;: Before &lt;del&gt;After&lt;/del&gt; having this issue:     Please force a crash by pressing &lt;b&gt;F3 + C&lt;/b&gt; for &lt;b&gt;10 seconds&lt;/b&gt; while in-game and attach the crash report (&lt;tt&gt;&lt;a href=&quot;http://hopper.minecraft.net/help/finding-minecraft-data-folder&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;minecraft/crash-reports/crash-&amp;lt;DATE&amp;gt;-client.txt&lt;/a&gt;&lt;/tt&gt;) here.&lt;/p&gt;


&lt;p&gt;    Please attach the &lt;b&gt;complete&lt;/b&gt; output of the &quot;Game Output (Your Minecraft name) &quot; which can be found on the fourth tab of the &lt;em&gt;launcher&lt;/em&gt;.&lt;/p&gt;



&lt;p&gt;    If the launcher closes after game start, please edit your profile and select &quot;Launcher visibility&quot; then, &quot;Keep the launcher open&quot;.&lt;/p&gt;

&lt;p&gt;That can be a memory issue, see e.g. &lt;a href=&quot;https://bugs.mojang.com/browse/MC-78028&quot; title=&quot;Extreme lag on all single player worlds 1.8.3&quot; class=&quot;issue-link&quot; data-issue-key=&quot;MC-78028&quot;&gt;&lt;del&gt;MC-78028&lt;/del&gt;&lt;/a&gt;&lt;/p&gt;</comment>

Thought I was loosing whats left of my mind as was usually minor tasks lost that I thought I did but couldn&apos;t be sure. Then some changes I made to a redstone contraption including changing item counts in some hopper and droppers didn&apos;t save. I clearly remember doing the math on them item counts thrice. This world has not been touched with an external editor and was never downgraded.&lt;/p&gt;</comment>

However what I have noticed is items disappear when you login a 1.8 world with a 1.7 profile loaded. This is probably because the new formats which may not be compatible.&lt;/p&gt;

&lt;p&gt;From searches I have found that the items are unreplacable. So for other users; take this as a warning.&lt;/p&gt;</comment>
                            <comment id="204833" author="galaxy_2alex" created="Thu, 23 Oct 2014 21:57:59 +0200"  >&lt;p&gt;Is this still a concern in the &lt;em&gt;current Minecraft version&lt;/em&gt; &lt;b&gt;1.8.1 Prerelease 3&lt;/b&gt; / Launcher version &lt;b&gt;1.5.3&lt;/b&gt; or later? If so, please &lt;em&gt;update the affected versions&lt;/em&gt; in order to best aid Mojang ensuring bugs are still valid in the latest releases/pre-releases.&lt;/p&gt;</comment>
                            <comment id="159929" author="anaklusmosbrony2.34" created="Sun, 25 May 2014 06:53:51 +0200"  >&lt;p&gt;I was getting this in the current snapshot- 14w21b. At first I thought it was an entity problem- I was just dropping things and reclogging, wanting to use MCEDIT. (maybe my old version of MCEDIT triggered it?) Then my blocks wouldn&apos;t save progress either, but my inventory would. &lt;/p&gt;

&lt;p&gt;After finding people with similar issues on a forum, I deleted everything from &quot;.minecraft&quot; except my saves, stopped using MCEDIT, and I enter &amp;amp; exit the nether right before saving and quitting now. It saves my progress again, but I don&apos;t know which, if any, of my actions resolved it. I hope this helps you guys isolate the issue, but I realize I&apos;m being rather vague.&lt;/p&gt;</comment>

                            <comment id="135681" author="isle" created="Mon, 27 Jan 2014 08:30:06 +0100"  >&lt;p&gt;I think the reason for this is the local server hasn&apos;t  finished shutting down when you get to the title screen. since about 1.3, when quitting a world, i&apos;ll run task manager and wait till the cpu usage goes down before doing anything on the title screen. &lt;/p&gt;</comment>
                            <comment id="129376" author="mysticmight" created="Tue, 7 Jan 2014 04:19:22 +0100"  >&lt;p&gt;I thought it was fixed for me atleast in 1.7.2 and 1.7.1, but then yesterday I logged on singleplayer and a sign was missing. It was the last thing I had placed in a previous session. This happened in 1.7.4, so I don&apos;t know whether 1.7.2 was fixed or not.&lt;/p&gt;</comment>

&lt;p&gt;Confirmed in 1.7.1&lt;/p&gt;</comment>
                            <comment id="108122" author="mysticmight" created="Tue, 1 Oct 2013 11:31:53 +0200"  >&lt;p&gt;I have evidence of this bug in snapshots. If I can attach these, just ask. (i.e. version 1.6.4)&lt;/p&gt;

&lt;p&gt;Edit:&lt;br/&gt;
Upon reviewing the snapshots, they do not display much detail of the bug (however a video would). So these snapshots would be of little use.&lt;/p&gt;</comment>

The descripted error already appears. The world status, including the recently added items in a chest inventory, is saved incomplete. Waiting a few minutes before leaving the game to the main menu seems to increase the chance of correct saving. But it is not reliable. Please, create a boringly normal, but working save button, even though the game is somewhat less novel.&lt;/p&gt;</comment>

&lt;p&gt;The current release version of Minecraft, 1.4.7, no longer has this issue. I think it was actually resolved by a prior version, possibly 1.4.5.&lt;/p&gt;

&lt;p&gt;I can confirm that it is definitely resolved under 1.4.7, however, and my world saves appear to persist almost immediately &lt;img class=&quot;emoticon&quot; src=&quot;https://bugs.mojang.com/images/icons/emoticons/wink.png&quot; height=&quot;16&quot; width=&quot;16&quot; align=&quot;absmiddle&quot; alt=&quot;&quot; border=&quot;0&quot;/&gt;&lt;/p&gt;

&lt;p&gt;Just try not to loose the fix in a stray code branch &lt;img class=&quot;emoticon&quot; src=&quot;https://bugs.mojang.com/images/icons/emoticons/wink.png&quot; height=&quot;16&quot; width=&quot;16&quot; align=&quot;absmiddle&quot; alt=&quot;&quot; border=&quot;0&quot;/&gt;&lt;/p&gt;</comment>
                            <comment id="52734" author="bljat" created="Thu, 14 Mar 2013 03:37:25 +0100"  >&lt;p&gt;Is this still a concern in the current Minecraft version? If so, please update the affected versions in order to best aid Mojang ensuring bugs are still valid in the latest releases/pre-releases.&lt;/p&gt;</comment>
                            <comment id="21455" author="vanhart" created="Wed, 14 Nov 2012 17:30:07 +0100"  >&lt;p&gt;Update : &lt;/p&gt;

&lt;p&gt;Note : it was possible to get reasonably reliable persistence behaviour under 1.4.2 hitting ESC, waiting 30 sec, clicking save, waiting 30 sec and going back into the game. However the reliability of this was only about 75%.&lt;/p&gt;

&lt;p&gt;Under the just-released version 1.4.4 the behaviour is still occasionally reproducible, especially when saving the diggings of just a few blocks. The game save behaviour is now about 90% reliable without waiting for the &quot;silent save&quot; to complete.&lt;/p&gt;

&lt;p&gt;Clearly whatever it was, it got improved by the 1.4.4 release, but the underlying cause is still lurking about. &lt;/p&gt;

&lt;p&gt;The &quot;Saving game...&quot; message is still conspicuously absent.&lt;/p&gt;

&lt;p&gt;Fixed? No.&lt;/p&gt;

&lt;p&gt;More reliable? Yes. &lt;/p&gt;

&lt;p&gt;Please keep this issue on the front burner &lt;img class=&quot;emoticon&quot; src=&quot;https://bugs.mojang.com/images/icons/emoticons/wink.png&quot; height=&quot;16&quot; width=&quot;16&quot; align=&quot;absmiddle&quot; alt=&quot;&quot; border=&quot;0&quot;/&gt;&lt;/p&gt;</comment>

                            <comment id="20935" author="vanhart" created="Mon, 12 Nov 2012 13:47:15 +0100"  >&lt;p&gt;I am also experiencing this issue since the 1.4.2 live release on previously generated and newly generated worlds.&lt;/p&gt;

&lt;p&gt;The behaviour is duplicated under both java 6.0 and the most recent Java 7 update 9 release. (tried updating, made no difference).&lt;/p&gt;

&lt;p&gt;The behaviour is duplicated wether minecraft is running in the standalone launcher or the applet on minecraft.net/play.&lt;/p&gt;

&lt;p&gt;OS : WinXP&lt;br/&gt;
CPU: Singlecore Athlon FX64&lt;br/&gt;
JRE: V7 Update 9 (build 1.7.0_09-b05)&lt;br/&gt;
Browser : Firefox 16.0.2&lt;/p&gt;

&lt;p&gt;Notable behaviour:&lt;/p&gt;

&lt;p&gt;The saved game &lt;b&gt;appears&lt;/b&gt; to act as if there are two conflicting versions of the saved block state, which are persisted or loaded at random, depending on some unknown factor.&lt;/p&gt;

&lt;p&gt;Nothing I&apos;ve tried so far appears to give stable saved results, however once a set of blocks changes in &quot;both&quot; versions, the loaded results are consistent.&lt;/p&gt;

&lt;p&gt;The versions don&apos;t appear to &quot;toggle&quot; between consecutive loads, but seem to depend on some random factor.&lt;/p&gt;

&lt;p&gt;More info to follow as I go...&lt;/p&gt;

I have tried to re-install multiple times and even tried creating new worlds but it never works.
