Combat issues

I'm having issues with Franz and combat. So far, he's gotten damage dice incorrect, damage type incorrect, status effects have changed from one round of combat to the next (going from the effected having disadvantage on an attack roll against the caster to the caster having advantage on their attack roll against the effect, this was with Chill Touch) He also doesn't do a good job at controlling npcs in your party during combat, going multiple rounds without them doing anything or saying a npc is poised to attack instead of just having them attack. There's also a glitch that causes a party member to take the damage they deal, I'll get a screenshot next time it happens but in the area that detects dice roll I'll do damage with an attack and that area will have a message saying I did the damage to myself and not what I attacked.
