So this is definitely not a glitch!
What is happening is on this Sequence node is the Decorator is saying “False” and cannot continue down. The red bar shows us that.
On the OTHER side, “Attack Range” is returning False, preventing it from continuing down.
The behavior tree isn’t ever reaching a task to execute. What I understand from this is The Target is set, but is out of range, so it cannot do anything, and sits at root until one of those turns true.
I hope that makes sense!
