Put the summary of the bug you're having here

What I expected to happen was...:
I open a chest and press my inventory key to close (set to '8' for me)

What actually happened was...:
Before the inventory of the chest closes, the game crashes. It started happening may every other time, but happening everytime now. i can just open a chest and go to close it, game crashes.

I'm on my multiplayer server. I've restarted the server and this does not change anything.
