Regular Crash after engine error, Pathfinding/AI related?

Summary:

After several minutes of gameplay, an error box will pop up with the following:

release-949 (x64)[M]
stonehearth/components/lease/lease_component.lua:62: attempt to index field 'owner' (a nil value)
stack traceback:
	[C]: ?
	stonehearth/components/lease/lease_component.lua:62: in function <stonehearth/components/lease/lease_component.lua:57>
	(tail call): ?
	stonehearth/ai/actions/reserve_entity.lua:33: in function <stonehearth/ai/actions/reserve_entity.lua:21>

	stonehearth/components/pathfinder/astar_search.lua:135: in function <stonehearth/components/pathfinder/astar_search.lua:120>
	(tail call): ?

within a few mins after this error, a screen freeze and CTD is always guaranteed. I keep making game progress in spite of this, and each of my subsequent saves errors and crashes in about the same timeframe, unless gameplay is paused. No crash.dmp generated.

Sorry can’t upload files

Can you try doing a “Town Alert” action and then resume? That could let the Hearthlings drop any items they are carrying, in case one of them is looking for a certain item being held. It may be that there is a blocked off item somewhere also, which needs a ladder placed to reach it.

Maybe it´s the crafter queues mod
