AI Behavior stop if spawned

Hello eveyrone !

I’m working on the AI of our game, and I followed 's tutorial on the AI (since I know nothing on this), and it works just as we need for our game.

The only problem is, the AI does not happend to have the same behavior if spawned or already placed in the world.
Basically, what the AI is supposed to do is move between points, and do a loop on all thoose points, starting by point 0. Both AI goes to point 0, but the spawned one does not goes beyond this point. I already changed the Auto Possess AI thing in my character BP, but the problem does not come from this. I know it for sure, because it has sighting (the AI), and the AI sees the player, it start chasing it, spawned or not. But for some reason, it wont move between each points.

Here is a video showing what I mean :
And here is a link to a light version of the project:

Update on this: the problem still persist… Here is a new video showing what happens when the game is run, and I access the Behavior tree. The already placed one is working perfectly, while the spawned one goes crazy on the instructions : - YouTube
