I've searched everywhere trying to find where I can submit a bug report on the matter, but this is where I do it I'm at a complete loss of where to goto.

My mission quest line broke days ago when several missions completed at once due to all of them already being done, and perhaps due to a game update that  when it occurred the same dungeon area kept playing over and over and over and over again never letting me progress normally past it, and that is where the item I need to complete the quest is. The item is an easy drop to get, but it never registers against the mission.

The capaign mission is simple:  win gauntlets with ATK (%) as the primary stat from stage 4 of the Sewers of Arnoc on normal.

I've done the mission so many times over countless log ins and computer restarts. I've even removed the game from the computer and re-installed it. I've even tried running the entire dungeon from stage 1 past stage 4, a few times. I get the guantets as drop easy enough, but never counts against the mission despite counting towards challenge artifact quests.

The only thing I haven't done yet, is completely quit the game.

I need help to resolve this. Kind of need mission quests.
