Approx. a month ago I started a save with some friends. There where some other mods but nothing major except renai transportation.
But now we want to continue with the save but factorio no longer starts up with this mod enabled. I've disabled all mods except this one and this is the error I get:
Failed to load mods: Error while running setup for entity prototype "cliff" (cliff): Invalid cliff bounding box: cliff AABB is completely outside of the cliffs position.
