after an npc was hunting and moved to the next task it gets stuck in the hunting pose. the bow itself is no longer present as tool.
in this state the npc can't access any container anymore. ie. can't eat, can't drop iff/pick up resources, can't swap gear. the npc becomes useless.
the state resets after a game restart.
i started noticing this behaviour after setting the ranged aiming mode to toggle. however i'm not sure this is the cause.
toggling that setting during gameplay doesn't fix the behaviour.
