Hello.
I have simple AIMoveTo player position. AI is going to the player, but function is returning OnFail - Aborted all the time, while AI is moving. I think it is incorrect, but I don’t know why it is working with this strange results.
It could be from navmesh settings, did you check your navmesh? maybe the point where ai try to go is not existed on navmesh. Try to debug with location node.
On flat surface with NavMesh I have the same result. The same with location node. And as I said, AI is working good.
