&lt;p&gt;It was a bug, not just a &quot;bug&quot;. And it had a real downside (read my earlier comments for one that lead to deaths). Granted, it would have been a nice (somewhat) technical application if it had worked right. (See what I did there? &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;If you want something peculiar similar to non-flowing water block for &quot;a nice technical application&quot;, request for a new feature - a proper new block that everyone knows how it will behave. Although I have hard time figuring out how to thematically make a possibly floating non-flowing water block... it might need to be something else than water, but similar behavior. &quot;Magic floater&quot; or some such. It would not even need to make your drown in it.&lt;/p&gt;</comment>

&lt;p&gt;To reproduce this effect:&lt;br/&gt;
1. Place a row of ice blocks&lt;br/&gt;
2. Place a row of fire next to that&lt;br/&gt;
3. After ice melts, it will not flow&lt;br/&gt;
4. If another ice block melts or fire block disappears next to the water, it will flow&lt;/p&gt;</comment>

If you use the /give command to get and place them both, you&apos;ll notice that the &quot;flowing&quot; water behaves like water placed from a bucket, while the &quot;static&quot; water acts like the issue case seen here - not flowing until it receives an update.  This leaves me to conclude that melting ice replaces itself with the incorrect block.&lt;/p&gt;

&lt;p&gt;I can understand why ice may have melted into static water in the past, since all naturally-generated bodies of water were static and any tampering with them would cause them to be forever flowing, but didn&apos;t they fix water source mechanics in 1.5?&lt;/p&gt;</comment>
                            <comment id="83076" author="bugi74" created="Fri, 5 Jul 2013 07:33:42 +0200"  >&lt;p&gt;@Shea: If that ice block is not surrounded by other water, does the resulting flowing water block stay around, or just dry up? Just as easy and the &quot;correct&quot; solution is to simply add a tiny bit delayed block update to the the melting process. (Well, I haven&apos;t tested that, but at least sounds obvious.)&lt;/p&gt;</comment>

&lt;p&gt;The problem with keeping bugs because some have found them useful is that they tend to make design and coding more and more difficult in future. That is, you&apos;ll get more bugs in future, and/or slower development as they try to work around bugs that are wanted to kept around.&lt;/p&gt;

&lt;p&gt;It would be better to fix this and instead develop a water source that will not flow in any case.&lt;/p&gt;</comment>

I can&apos;t say if it works as intended or not, Mojang has to tell us. But I think, this should stay, as it&apos;s useful and pretty much every minecraft player is using this.&lt;/p&gt;</comment>
                            <comment id="36972" author="bugi74" created="Tue, 15 Jan 2013 17:11:48 +0100"  >&lt;p&gt;Sid Ben: It is quite likely a bug; I haven&apos;t played much with ice blocks, but iirc, they have worked differently before. (Some while ago I had to put some torches to melt occasionally freezing water sources to keep them flowing, so that I wouldn&apos;t die for a &quot;water elevator&quot; suddenly drying.)&lt;/p&gt;

&lt;p&gt;So yeah, auto-flowing source blocks do have benefits.&lt;/p&gt;

&lt;p&gt;Having means to have floating water sources could be nice, but lets not use bugs to that end.&lt;/p&gt;

&lt;p&gt;Also, whether a behaviour does or does not affect gameplay is irrelevant in deciding whether something is a bug or not, it only affects how severe the bug is. (Examples; minor visual glitches are bugs even if they are totally insignificant for gameplay; dying from a mob attack affects the gameplay quite severely, but is not a bug.)&lt;/p&gt;</comment>
                            <comment id="36968" author="sidben" created="Tue, 15 Jan 2013 16:48:56 +0100"  >&lt;p&gt;I wouldn&apos;t call this a bug, it doesn&apos;t affect gameplay since you just need to cause a block update to make the water flow.&lt;/p&gt;

&lt;p&gt;The current way allows you to have floating water sources. Fixing this would take that away, with no benefits.&lt;/p&gt;

&lt;p&gt;In my opinion, this is &quot;work as intended&quot;.&lt;/p&gt;</comment>

The water flows when one of the neighbor blocks is updated.&lt;/p&gt;</comment>
