This bug has been happening for at least 2 months now. Every time my husband and I play Dungeons on multiplayer, the difficulty automatically jumps back to the highest available difficulty, no matter the difficulty we have selected. We are currently in Apocalypse around Apocalypse 5 or so and we cannot select a difficulty below 7. This is not just a visual bug as the levels are clearly more difficult than they should be if they were the level we had selected.
