It might be my slow pc but after a thug reaches out to mezz in combat the game screen would bug out, freeze and or crash all three making the game unplayable. I ran into this bug just after getting the hypnosis ear pieces and after losing once and then going back into battle.
Think that's local to your machine then. Just did some quick testing and I'm not seeing anything obvious. This new update shouldn't have changed anything regarding the art assets for the fights, I just removed a bunch of unused stock art. I'll keep an eye out if I get other reports though.
