Random Crashes in MP, Unexpected error

This ticket is invalid as it relates to a modded or 3rd party client/server.

• Any non-standard client/server build needs to be taken up with the appropriate team, not Mojang.

• Any plugin issues need to be addressed to the plugin creator.

• This site is for addressing issues related to the base unmodded Minecraft.

I could not find any existing issue that contains any of the crashes mentioned here. However, all of the crash reports that you have provided are from a modded version of Minecraft. Please try to reproduce the crash in a vanilla (non-modded) version of Minecraft and attach that report or this may be dismissed as being caused by a mod. You can view all information known about this specific crash at MCX-729.

IT may be modded, but i can join other servers

If it still crashes with an unmodded client feel free to create a new ticket.
