Well, those effects are tied to your character when you save. I can see how this could be a pain. Perhaps damage-based afflictions should be removed on level transition or even saving. Instead, I can just reduce the player's life to a certain amount. Though, he will always come out alive without the possibility of being dead locked.
Of course, if a person saves while they are surrounded by a bunch of creatures, then that is just a bad decision on their part.
For now, backup all of your save games. They are in the Deadly Dungeons folder of you device. If you can zip them up and send them to me then I can fix it for you.
You can also try fixing it yourself. Though, keep a backup of all the save games in case it doesn't work.
1. Copy all the save game files with your character's name on them to another location.
2. Start Deadly Dungeons.
3. Go to the Characters screen and browse to your character.
4. Press 'New Game'.
5. After you load up in a new game, quit to the menu and exit Deadly Dungeons.
6. Copy the global save file and level save files back to the DeadlyDungeons folder on your device.
7. Go back to the character in Deadly Dungeons and select Continue.
This may work for you.
