1.1.0: Server crashes




What is the bug:
Hi there.
I would like to report a bug that is currently ruining my server and it is about time i need to do something about it.

My server crashes every single time one of my friends encounter one of the big horses(The Ultimate Unicorn Mod) and there is a npc riding on them

I am sorry if i am not being total clear of the problem - its quite hard to explain as english is not my main language


Mod & Version:
Mindcrack 1.1.0
