Hi there. I've had Dark Sun 2 for quite a while now but only recently have started playing it. The good thing about this game is that when you're stuck in
one area you can go to the next and come back to it later. However I am now 
stuck in multiple areas and have no idea how to procede. Worse.. many of the 
stucks seem like bugs..
 
1) I was only able to go to TWO places in the mines. ie: all exits either leads to one or the other. This is really driving me nuts cause I know there are
other places  you can go to in the mines.
 
2) How do you get out of the snake pit where there are a bunch of snake eggs?
you get it by trying to get to the treasure in Traxiss's room but there's a pit.

3) How do you get Traxiss's treasure?
 
4) Are you suppose to negotiate with the Yuan-Ti? I couldn't get the letter to
work so I just slaughtered them all, including ol' El. 
 
5) After I rescue Jann from the other dimension I get stuck in the middle of the
desert and I can'
t see myself. bug???
 
6) The same bug applies when I try to get back to the halfling caves after I
kill Runner (ie: the narrow slot in the underground)
 
7) I have the key nd the sword 'Bloodletter' from Under Tyr but can't figure out
what the heck to do with them.
 
If anyone can answer some or all of these questions, please mail me, I'd REALLY
like to talk to you.
 
Thanx in advance
