The detection for that would be to call pathfinding for each adjacent tile to the one you'd want to build and if there's no path, one...

Ok, it's actually crashing no matter what I do, any new save I do is crashing no matter what I do...
I found something, though. When I deconstruct nursery tiles, the ants stay. They're not removed from the map and keep walking around. And it seems as if removing nursery tiles and then saving...

After the mission, it even crashes while trying to return to the formicarium. A reload after the crash, crashes also.
