Expected to collect delve chest after beating boss room. Instead, it then showed that only the initial room had been beaten. It was in Stonesong Eyrie Level 380. I beat the Intro Room, then IV-Buried Graveyard, then the Boss Room. Then, instead of showing the delve chest to collect, I was given the option of running away to collect a level 1 delve chest. Both the Buried Graveyard and the Boss Room showed as if I hadn’t fought them yet. I had to fight Buried Graveyard again (or I could have chosen a different path at this point) before I was allowed to attack the Boss Room a second time. So, instead of fighting 3 battles to complete the delve, I was forced to fight 5.
How often does this happen? When did it begin happening?
This was the only time I’ve encountered this issue.
