How do I move AI via a behavior tree?

Hi Peeps!

Getting a rather annoying issue that wasn’t happening in 4.0.2 - the below blueprint is sent through a Behaviour tree - the tree is still firing correctly as the print string is displaying upon each spawn of the enemy - however they are no longer moving toward the player character as before.

All I want them to do is move towards the player character until they reach it. The collision and other stuff is still working.

Any ideas?

Have you solved this yet, if not have you tried adding a navigation mesh?

This goes over AI Navigation.
