Bug: getting error messages when shepherd makes tune

I keep getting error messages when the shepherd makes the tune. This is what it says stonehearth/ai/observers/aggro_observers.luac:52: attempt to index local ‘traces’ (a nil value). My game is in peaceful by the way not sure if that makes a difference or not hope this helps.
