The character starts navigating the mesh, runs into a blockade, destroys it then the BT gets stuck between setting the key (object, actor), which it does so successfully, and moving to the key object, with the resulting behavior just a stationary skeleton awating orders.
NB. The screenshot only shows the setter node but in live play it does flit between that and the move to node. The move to node is also set to MonumentTarget. Acceptable radius is set to something low like 10.
Any ideas?
