With the 1.4.1.0 alpha version and Sophisticated Wolves (the latest, version 3.6.4) installed, i get a very occasional issue where a wolf appears as only its shadow (no wolf rendered). Looking at the wolf causes the game to crash.
Here is the crash log:

Hmm... this looks like it could be a Waila incompatibility. I'll look into it.

Merged with #13, #21, #34, #38 in #41
