Hi,
I very recently decided to give PvP a try and having conquered a small barren colony, it seems it has been under attack 4 times.

Yet it doesn't seem to count towards the achievements list.

Is that a bug or do I have to wait for either the remaining time to lapse or the island to be lost to someone else before the achievement is awarded?
Edit: I now just received the notification that a regular colony has been successfully defended and the achievement awarded. So why not on the small colony?
I hope to receive some feedback from either BB or fellow players. Cheers!
