I need the full log (including the version number).
So this is on the server-side, not the client side?

I have a confirmed full report of this crash from someone else. This is a legitimate crash and I'm looking into it now.

Hey,

Sorry long reply, kinda posted this and forgot it was here. Haha. xD

This problem should be fixed in the next and latest update for 1.7.10 (once I upload it to CurseForge)
