This is the character with whom it's happening.
I was portalled to a dungeon called Korelamnir and it's based on the sand tunnels, just without the worms, but it's expected that you dig yourself as well.
On lvl 3 I had a very small dungeon so I decided to dig to see if I could find more, but after about 15 grids I decided to go back. Somehow when I wanted to dig from where I came from it failed and I ended up in the middle of the sand with nowhere to go. I tried to dig, but that didn't work anymore somehow so I died. Well that certainly was a lame death, but that's why I don't play roguelike

Anyways I had to return to this dungeon since it was a farportal, but after I returned the game went crazy and I can't see myself anymore. I can see that the mobs are moving by themselves very fast, but turns don't seem to pass though. I tried rod of recall, or phase door, but all my skills stopped working.
Please help me out. It's just my 2nd character that got this far and a 100% certain winner since I can just bump bosses to death. Obviously time for me to move to nightmare difficulty, but I want to finish this character as it's been great fun.
