AI Duplicate wont move

Hello everyone! I want to know weather or not this is a bug or not. When my AI is alone by itself with the player then it will chase me. But if I duplicate more AI as team members then none of them will work.

I would also like to mention how this has never happened before. And all of a sudden I come across this now.

Also when I duplicate AI a bunch of errors come up

I have the same issue. My BT trees randomly stop playing. They play again when I hit AIs capsule or by enabling brain again. I haven’t had this issue before in earlier engine versions.
Anyone else has this issue?

I kind of found something that is weird. Every time two AI are near each other they will not chase me. Am I doing something wrong in the AI Controller.

Fixed everything by using checking if actor has tag then on true we would set CH and Bool.
