Normaly I would know how to fix these, but this one just totaly threw me off

I've been hunting down that error for ages... as has the CE community in general (at least 5 or 6 threads at Gearbox about it...)

The only thing I've picked up from them is the possibility of a physics tag being involved. Though, if you open up tool in notepad and ctrl+f the error (something I always do when dealing with these obscure errors - it may be the equalivalent of voodoo but sometimes it helps me find a solution) it's next to a bunch of memory size errors.
