Behavior Tree not working

I was following the Behavior Tree Starter guide and I can not get it to work. I have recreated this behavior tree 3 times and have not gotten anywhere. At one point I had the AI walking around but it only went to one point and stopped and wouldn’t move anymore. Now I have this issue. I am having a hard time finding a good guide on how to figure out behavior trees, any help will be much appreciated.

I think I am having the same issue. I followed that tutorial and it seems like the behavior tree is not run. (I attached a breakpoint to the first selector node and it never brakes.)

I am using 4.9. My AI_Controller is using the Blackboard asset and is running the behaviour tree (Adding a breakpoint causes a break). I have set the character to use the AI_Controller as default and to be autopossessed by AI when placed in World or spawned. The character is placed in the level as well.
