0.5.3: Fighting Vitja 2nd tier game freezes

OS: Steam Proton
Instability 0
Not sure why it is freezing. It seems to happen when any damage is attempted to be done to the enemies.

Freezes on Windows as well.
Can’t get past with spell damage, debuffs, or attacks.

Found the problem, thanks! I’ll start compiling a patch now - should be ready in an hour or so.
