Guild Wars 2

I randomly get progress in weapon master achievements.
Few days ago I noticed my staff weapon master appeared in achievements close to completion. I looked at it from time to time and it seemed to grow a little every now and then. I though to myself that maybe it reads my longbow/great sword as staff so I killed group of ~7 enemies and got +1 to achievement progress so not exactly.
Now I got first tier hammer achievement even though Im still only using lb/gs. It seems to grow by itself from time to time.
- both times I was without party
- once I was in open world, other time I was in story instance
- never saw anyone nearby wielding corresponding weapons – players and npc alike
- I play ordinary ranger(no druid)
- first I completed 5k staff kills, then got 100 hammer kills

The second time I played through this instance I noticed that after talk to magister my health wasnt regerating (like I was still in combat) so maybe Braham have hard time starting conversation because of combat? Dodging next to him somehow got it triggered, idk
My health started regenerating once we got back to team

HOLY KITTEN.

It wouldnt hurt that much if I didnt struggled with the same bug year ago…

I’ve beaten Maddie and Caiwyn the Corsair and their moves are still locked, didnt checked others tho, but propably they are bugged too
