A zombie scientist used a special attack through reinforced glass. I’m not sure which since they have multiple specials. This has happened before but I was unsure of the cause. I can’t get it to repeat in the tutorial. In case its relevant, I was unlocking the doors of the cells In a prisoner containment facility and it crashed the turn after I exited the console. I can post a save if necessary.
Also, plastic arrows have the worst accuracy ever, the unfletched shafts are more accurate. It’s probably an extra 2 in the dispersion value.
