Random Error After Placing Sheep Pasture

I’m new to these posting on these forums but I’ve been playing Stonehearth off and on for a couple years. The ACE updates have been really good and generally getting more and more stable. The one error I have gotten so far on this new save is below. it first appeared after placing a 25*25 area for sheep. There are sheep near my town and I’m not familiar with anything in the error below. Any help is appreciated.
