"Rise to the challenges" achievement bug

[Riku]

I am trying to get this achievement and have completed all waves on the:
North Ford Bog Battle Arena
Feldcroft Battle Arena

Additionally I have also completed the Dark Arts Battle Arena which comes with Deluxe edition of the game.

But I did not get the achievement after completing the arenas.

Additionally, my Dark Arts battle arena was marked as complete on the map when I first finished it but the other two base game arenas are not getting marked as complete on the map.

I have completed the arena battles on both of these arenas multiple times and I also think I got an outfit reward (Ashwinder's Outfit I think) but no achievement.

PS: I am past the ending.

Same for me, completed dark arts, got a tick there, but other arenas are not being marked somehow

Bugged for me too, when I played Ravenclaw, got the dark arts arena marked but not the other 2.
However when I switched to Slythern, both arenas got check mark and achievment popped.
Which house did you choose when this achievemnet bugged for you?

I had similar problems, achievement not popping after finishing both arenas. I quit the game, came back after a few hours and did it again, this time it worked. My arenas still don't have marks though. Playing as Slytherin.

Same, got the outfit rewards but no checkmarks except for Dark Arts Arena and no achievement. Playing as Ravenclaw and completed the 2 normal arenas after the main story
Edit: Reinstalling game and playing the arenas again worked

My arena bugged. When I killed the big spider it said challenge complete, however a little spider was still trying to kill me. Didn't think anything of it until I saw I didn't have the outfit. You will have to go back and do it again.

Make sure the acromantula's minion spiders are dead before you finish it off or you won't get the achievement or the thief's coat!
