Why does mannequin not move while in play?

I recently changed my blueprint to include a weapon in its hand. When I compiled it and saved and ran it. The mannequin now no longer walks nor runs or anything. It just kinda floats to where it is heading. How come?

Check if the animation blueprint is set on the character. If it is set to none then you need to reload it with the correct anim blueprint.

Tried that and did not owrk.
