Guild Wars 2

So I’ve been trying to figure out what T3 boss to try getting 5 gambits on. So I’ve just been doing them to see which I can do easiest. I did Deadeye Dunwell on my Warrior. Just to get one achievement I put on the exhaustion gambit. After I killed him I noticed I got the meta achievement which confused me. It confused me because I needed two more achievements to get that, not one. So I check and I also got Humble Victor achievement.

Same here with Deadeye too.

I can confirm that this bug is still active, I did the On Fire gambit with Deadeye last night and it gave me the Humble Victor achievement.
