ToV - wurms - warping into walls

[Orruar]

The other day we noticed that wurms had a tendency to warp into walls when pulled through small openings in halls of testing (east ToV). For the most part this was fine, as they'd warp out again. But if they happened to be in summoning range, this leads to some serious problems. For instance, the doors leading out of the main entry pit (where 2 wurms spawn) were small enough that this would occur.
