Update: Dungeon is back
Restart the game if you still don’t see it.
If you noticed that the Dungeon has disappeared, you are not alone. Dungeons usually appear at the last 2 weeks of the monthly event quest and you get to play 5 rounds each month. However, this time it just vanished after 2 rounds. So is it intended?
No, it is probably a bug. Kabam has no idea so far what happened, but they are looking into it. One of the Kabam Mode “Kabam Vydious” already mentioned that they have informed the team about this issue. There is already an open thread on the Official Forum if you want to stay up to date.
