Include me as well. I have the exact same bug. Everything was fine when I only had 3 oil/coalshale extractors working in a block just south of my base. When I added two more for a total of 5 extractors, the game will crash the second I enter that block/Region.
I have tried all the steps to rebuild those blocks and region independently, together, and everything else I can try; however, the moment you cross into that block the game crashes to desktop.
So, it appears the safe limit is 3 extractors; go up more and it will cause some error that crashes the mod when entering the block.
Hopefully it can be fixed when the update occurs. 😊 I LOVE THIS MOD!
