Found a bug in the latest version. When starting a standard new game with the Adventurer you get the Daily Dungeon timer as well. When doing that with the Aristocrat you get INVALID on that spot on the screen and with the Ranger and Warrior you also get the timer. Didn't test the others.
Not a bug, maybe just bad UI/UX from my part. When you do a normal dungeon, there's a separate leaderboard than the daily dungeon. For this leaderboard, I didn't want to let users use Aristocrat because it's basically an 'easy mode' class. That's why it shows INVALID when using the Aristocrat. It will also happen if you use a cheat btw
