Third person character doesn't move after extending Blueprint only project

Hello guys,

After working through the Unreal 4 course on udemy (i just had to give them credits!)
I am now trying to extend a BluePrint only project with some C++ and NPC AI movments.

After converting the project using this: A new, community-hosted Unreal Engine Wiki - Announcements and Releases - Unreal Engine Forums

I added the Nav Mesh, imported first and third person c++ boiler code from the engine and wrote a simple behavior tree. The problem is my third person character is not moving and I have no idea why not.

When running the game I can see that the behavior tree is being executed and that my custom AI class is possessing the third person character.

What else could be the problem?

very bizarre bug; that just vanished after rebooting the PC. (reboot if you have the same problem… i guess :frowning:
