So I have a problem. I'm making a map, but when I add perk prefabs (UGX Modtools Patch, or from root/map_source/zombiemode) I always get this error after compiling and loading the map:

Unhandled exception caught

It's really annoying, plus I have T4M, so it shouldn't b a memory or fx limit problem. But as soon as I remove the perk in radiant and load up again it's fine. I don't know why this is happening and I would like some pointers. I'm using UGX Mod 1.1 on the map if that could have something to do with it.
