&lt;ul&gt;
	&lt;li&gt;Any non-standard client/server build needs to be taken up with the appropriate team, not Mojang.&lt;/li&gt;
	&lt;li&gt;Any plugin issues need to be addressed to the plugin creator.&lt;/li&gt;
	&lt;li&gt;This site is for addressing issues related to the base unmodded MineCraft.&lt;/li&gt;
