There has been problems with the Improperly Placed junk for a little while honestly. I have had the same two 18x18's outside Umbra for quite a few years and never had an issue. Some dude plopped down a house in front of one of them and mine goes to Improperly Placed and his does not... *shrugs* Don't see how his plot was allowed to be placed if it somehow threw mine into being Improper..
