Well, of course Pod Homes can be motivated. They're residential coin producing buildings, just like any other when it comes to motivation. Possibly your guildies/friends/neighbors haven't been aiding to the degree necessary for everything to get motivated/polished, and the Pod Homes have been missing out. And now maybe there's been an increase in aiding or you've eliminated some buildings that had a higher priority, so Pod Homes are higher on the priority list than they used to be. For whatever reason they're now being motivated, it is not a bug.
