I have the PC GoG version (latest v.2.0.119.430) and just hit this bug. If I don't go to Silverglen I'm fine, but if I do then it crashes & permanently freezes the game. Did the fix for this bug not make it into the GoG version or is there some easy fix?

Earlier in the game the white cat, Arhu, in Silverglen eventually could not be talked with or even clicked on with him constantly saying, "Psst. Source Hunter. Over here." However, it seemed trivial & I doubt is the cause of the Silverglen crash.
