No, I'd been at max population for several weeks, always showing 4520/4520.
Only adv I did was a lootspot, and that was no losses (although the 1r didn't add back in on return).
Nothing has changed on there, I haven't made troops, haven't llost any, and not built or destroyed any residences.
The only thing that has changed is the maintenance, so their so-called "fix" lasted less than 2 days.
