I'm trying to set up a simple AI for the enemy blueprint to make them target player's chosen character which is a parent of the main character BP

Well, I did add sight and damage senses to the AI and once I got in its sights, it stopped attacking completely. When I checked the BT, it was set to Chase Player but it was rapidly switching between ‘stop sense’ and ‘move to’ tasks, while not moving from its place.

I’m sure that I’ve messed something in the sequence order, conditions or something else entirely.
