I did the Asylum of the Fiends and the Demense of the Demon Spiders back to back in one session. There were4 or 5 empty minor chests in each one and there was no three skull boss at the end of either dungeon. The sigil chests worked fine though and I got a sigil from each. The Demense sigil was my second one. I did that dungeon a few days ago in a seperate session. I can’t remember but I don’t think the boss was there either. Definitely not this time.
