And I see I have save game import bugs because I forgot to patch before the new play through. I only got to the end of Act 1, but that's like 8-ish hours. Bah! I still love this game, so I will deal.
As I recall, the invincibility occurs mostly if you attack them "mid spawn" i.e. during the short time period after they have spawned but have not yet become active. This spawn lag was introduced to give the player time to react to enemy appearance.
Ah, that makes sense. The enemy waves is a bit off-putting, so I get that. TY.
I have some issues with my character getting stuck and unable to move in combat as well... usually, pausing the game for a few seconds and then going back into combat allows me to make him move again
sometimes you may need to do it a couple of times before it works. Not sure about the companions thing, though D: sometimes mine would just hang around and do nothing after killing only those enemies who were close to them. Sending them manually to fight other enemies usually fixed it. Not sure if that's the same issue you're having, though D:
TY, as well. Trying this worked!
