The Bone Pits error

So, about The Bone Pits...
I just lost my second character to them.
I just can’t load them. This is the second time it’s happened, and it’s in the same place too.

I created a new character and started from the beginning. I got it to level 24 and entered The Bone Pits again. There was some kind of error, and I had to restart.
Now, both of the characters that entered The Bone Pits can’t be used.

Has anyone else had the same problem?
