When I opened the game, it showed that the battle was already ongoing, but there were no sentinels present.

I highly suggest including the following features when in a dungeon:

1. Play Speed – This could be unlocked at a certain level, dungeon stage, or achievement. The game speed should return to normal after each battle so players can still manage their strategy, adjust positions, or recover health/armor as needed.

2. Skip Battle – I believe adding this feature could temporarily resolve the empty-sentinel battle issue and also improve the overall gameplay experience.

The battle is still ongoing as I’m composing this bug report, lol and currently in Dungeon 50.
