This ticket is invalid as it relates to a modified or third-party client, server, or launcher.

Any non-standard client/server/launcher build needs to be taken up with the appropriate team, not Mojang.
Any plugin issues need to be addressed to the creator of the plugin or resource pack.
This site is for addressing issues related to the base unmodded Minecraft; any modded system invalidates your ticket, unless the behavior can be reproduced without mods.
Additionally, if you have problems on large-scale modded servers, please report it to their site. It's probably not a bug in Minecraft.
