Bot AI/Behavior Tree Not Working (Blueprint)

So, I was following this tutorial(AI & NavMesh by Peter Newton). When I tried to translate it over to my game without his character controllers (it’s a flight/underwater game), the behavior tree seemingly goes haywire. The root, detect, patrol, and route nodes flash like crazy, as does the red bar on attack. The bot will not move to the waypoints or the player, it just stays in its starting position. Here’s an Imgur album of my blueprints, I figure it’s easier to view there because there’s a good number of pictures. As far as I can see, the code is the same as the tutorial, besides the replacement of his controller with my pawn. I’m also pretty sure the firing is done wrong, my teammate did that part for the player and it’s not complete.
