Well -
I've never tried this but it may be worth a shot -
If you send me a copy of your gamexx.sav ZIPPED or RARed, I can see if I can figure out how the information "stoned" is stored and see if I can remove it. Not sure that I will be able to but I'm willing to give it a try if you'd like.
Developing a new character from this point could actually be a lot of fun since the others will be there to protect the newbie. I often find that I will start a game, play for quite a while and then start over once I've really got the hang of the game.
and - as you have already learned - SAVE, SAVE, SAVE!! Multiple saves are a must!
