Guild Wars 2

Just a quick bug question since I cant seem to find the answer from anyone ingame.

I purchased the Mad King Costume during the halloween event and have it equiped on my level 80 necromancer, the problem I’m having is that whenever I try to brawl using the costume I can manage to get 1 or 2 hits in and then suddenly all my brawl buffs will reset without reason or warning. This happens even if my brawl hearts are full and is a regular but very random occurance, obviously it has the downside of me not being able to achieve a champion tag while brawling with it.

I’ve tried all the other tonics and transformations, the brawl mechanics all seem to work fine with those and anyone else I’ve seen with the Mad King Costume seems to have all their buffs functioning correctly.

Its not a huge issue since I picked it up just for looks originally and to have abit of fun toying around but I would like to know if its a known bug and if there’s a way to fix it.
