[1.1.1 Windows 7] Toxicologist combat crash

I had a perfectly normal extended day of play with a variety of specializations, mostly Toxicologist, but when I began playing again after a break this evening I started getting many, many, MANY hard program crashes during combat. This seems to be consistently when either Virus or Fermented Hops are being cast during the ends or starts of turns.

Please restart Steam to grab the hotfix!
