It seems to happen when a package of resource or behavior is placed on the map. It's happening in my world too. It's just an assumption, so far, from the tests I've done, this only happens on maps that already had resource and behavior packs installed before. Including one that changed fog settings, but I'm not sure, there's a map I tested, and the add-ons didn't change the fog, the bug happened anyway. It seems that the map is damaged in a certain way, it's strange, I'm having to migrate all my buildings to another map.
