I had an achievement listed to get 25 Allies, but it's suddenly gone. I was at about 11 last time I checked it. And I've removed a few Allies since then to clear up room to send out more invites. Maybe that's why it disappeared? I will continue to send out Ally invites and hope it reappears.
Anyone have a similar issue with an Achievement disappearing on them? I don't think the devs even check this forum, and if they do, they rarely reply, so I think we're on our own.
UPDATE: The achievement has reappeared and is at 12 out of 25. I think it disappeared because I removed some Allies from my list. To the devs, check out this bug. To any moderators on here, feel free to "close" this question.
