Hello again,
Don’t worry, these kinds of things happen all the time when you’re learning a new tool. It’s completely normal to miss small details, especially with Behavior Trees, where everything depends on references being properly connected and written correctly.
In this case, the problem is in the Move To node: the Target is ending up as None.
This usually happens because the Blackboard key name isn’t properly assigned when you set the attack state. Check inside your SetStateAsAttack and make sure the variable is using the exact correct KeyName. In your case it should be Player, and in mine it was AttackTarget.
If the name doesn’t match exactly, the Blackboard won’t store the reference and Move To won’t have anything to follow, which is why it gets stuck.
With that, the issue of it getting stuck on Move To should be resolved.
