Ok, I think there might be an issue with using a decorator for this functionality (I could be wrong). The way I set up my Bot is that I’m checking how far away I’m from the player → setting different bot states and based on the blackboard condition I’m activating different BTTasks. I think I had a similar issue when I tried using decorators. Here is a reference of how my Tree is set up. (Again this could be completely wrong).
Hopefully this helps you narrow down the problem.
