Mining drones has some things stored at -1000000, -1000000 that is out of bounds of the map, this chunk gets deleted and causes the mod to crash. Dont know if the mod can detect these entities to stop the chunk getting deleted, or just only delete chunks within 500000 tiles of spawn or something like that. Thanks
Took a look at it. The issue is that Mining Drones creates a chests at {1000000, 1000000} and does not chart that chunk. Delete Empty Chunks does not scan uncharted chunks for entities before deleting them. I would recommend that the author of Mining Drones create a separate surface to store such entities instead of hard-coding a position on the default surface.
