After a longer break I started on PvP again and I've changed my grand company from Maelstrom to Immortal Flames. Today I've done 5 Seal Rock frontlines and achieved 3 victories. Just now I noticed that those 3 wins did not count up to the frontline achievement "Behind Enemy Lines I" which grands a mount after 200 victories in any of the 3 grand companies. The number is still stuck at 21 from the times I was in the Maelstrom. Though the other frontline achievement for winning in the Immortal Flames only got higher by 3.
I don't think this is intended as Seal Rock should belong to the frontlines and should count up for "Behind Enemy Lines I" and "Behind Enemy Lines II", too.

Please have a look on it! Thank you!
