            <title>[MC-5209] Efficiency enchantment doesn&apos;t work on some blocks</title>
                <link>https://bugs.mojang.com/browse/MC-5209</link>
                <project id="10400" key="MC">Minecraft: Java Edition</project>
                    <description>&lt;p&gt;After the update to 1.4.6 using an efficiency IV or V diamond pickaxe on grass or an efficiency IV diamond shovel on glass or glowstone does not affect the speed even though &lt;b&gt;there is no report in the changelog that some bug related to this has been fixed or that the way enchanted tools work has changed in the update 1.4.6&lt;/b&gt;&lt;/p&gt;

&lt;p&gt;In 1.4.5 and previous versions these tools would mine these blocks instantly on point.&lt;/p&gt;</description>

Well, since it was Dinnerbone, the matter is over.&lt;/p&gt;</comment>

                            <comment id="30164" author="purple" created="Sat, 22 Dec 2012 20:14:54 +0100"  >&lt;p&gt;I made a valid objective argument to your subjective opinions (mod A says that it works as intended, mod B says that the opposite behavior works as intended) so I expect at least an answer that proves me wrong. Bottom line you are moderators not the development team so you could be wrong too (as already happened because Kumasasa in &lt;a href=&quot;https://bugs.mojang.com/browse/MC-2796&quot; title=&quot;Enchanted pickaxe works better than shovel&quot; class=&quot;issue-link&quot; data-issue-key=&quot;MC-2796&quot;&gt;&lt;del&gt;MC-2796&lt;/del&gt;&lt;/a&gt; and Mustek and Tails in &lt;a href=&quot;https://bugs.mojang.com/browse/MC-5209&quot; title=&quot;Efficiency enchantment doesn&amp;#39;t work on some blocks&quot; class=&quot;issue-link&quot; data-issue-key=&quot;MC-5209&quot;&gt;&lt;del&gt;MC-5209&lt;/del&gt;&lt;/a&gt; have conflicting opinions so only one side can be right).&lt;/p&gt;</comment>
                            <comment id="30146" author="purple" created="Sat, 22 Dec 2012 16:27:02 +0100"  >&lt;p&gt;There is no official statement that there where any changes that would affect the behavior of enchanted tools or about a bug fix neither in 1.4.6 nor on the 3 snapshots between 1.4.5 and 1.4.6&lt;br/&gt;
A link to a confirmed bug report of this bug (efficiency working on blocks that it shouldn&apos;t) would at least partially justify what you say. Instead I can only find &lt;a href=&quot;https://bugs.mojang.com/browse/MC-2796&quot; title=&quot;Enchanted pickaxe works better than shovel&quot; class=&quot;issue-link&quot; data-issue-key=&quot;MC-2796&quot;&gt;&lt;del&gt;MC-2796&lt;/del&gt;&lt;/a&gt; where a player reports that efficiency enchantment affects the efficiency of mining the wrong blocks and the mod closes it telling him that there is nothing wrong with this behavior.&lt;/p&gt;</comment>

                            <comment id="30138" author="mustek" created="Sat, 22 Dec 2012 15:19:42 +0100"  >&lt;p&gt;It&apos;s a bugfix, now they&apos;re only efficient on the blocks they were intended to break.&lt;/p&gt;</comment>
