I was on a level 17 or so Daily Realm, I cleaned it out, and I decided to use it to finally beat the Major Sigils I had collected so far. And I beat a bunch of them, until I lost a fight.
This defeat, inside a Daily Realm but after I’d beaten the DR, still reset my DR count. Not very fun, that’s a two or three real-world weeks’s worth setback. And it’s annoying: I had beaten the DR by that point.
So, is it a bug?
