my very old BTB houses on old 30 day buddy codes finally were found with this housing server glitch or whatever they have going on. They were immune to the original BTB bugged homes fix.
I also had an inactive accts house drop this past month. I always turn the acct back on to save the house but this time it fell in under three days from not being in a wear cycle when I left on a Friday (i checked) to being gone Monday when I logged back in. Decay is all messed up for sure.
