I went into Merlinmld's dungeon and killed about 1/2-3/4 of the defenders, but then when I crossed a tile occupied by the character in need of rescue, everything froze.
The screencap didn't pick up my mouse, but it's hovering right over my rogue and it's still the arrow, not the finger. I can't click on anything in the dungeon, whether it's a character, an item, or the next turn button. I can switch from character to character by clicking their icons in the bottom left, but all it does is highlight the character. The action options do not come up, I can't take another turn, and I have to exit to town and abandon all XP and items.
Tried again today, there was no rescue character, but same thing happened on the same tile:
Again, there is nothing I can do. The next turn button cannot be pressed, the characters cannot take any action, and the potions I used getting to that point was wasted gold I didn't earn back.
I really wish there was an option to exit dungeons early for a reduced amount of XP so we don't lose everything when something like this happens.
