Unique map cowards trial crash

me and 3 friends decided to run the unique map cowards trial got to the 3rd room and it crashed and kicked all 3 of us to desktop. I didnt look at any error I was in a hurry to get back in but I would be it was cause by just too much crap on the screen. monsters, loot, etc as we were desyning like crazy with all the projectiles milions of white items on the ground etc..... might need to tone it down a little or increase the size of the rooms or something.

Pretty damn annoying as this has never happened to us before but this is what betas are for i guess. just thought i would mention if in case no one has reported it.
