I built a map room in the highlands. All stability numbers are correct to build (In this case 40) but every night after server restart I am missing the same walls from my structure. The odd thing about is it my build is the identical on all 6 sides but only 2 of the sides have walls missing. The same 6 walls in total always go missing every morning. screenshots should help. I can take more if needed.
If it matters this is on PvE:C #3522 near the great dam
