Excellent, thanks for the advice. I managed to get lsv's decompressing and re-compressing on linux now smile .. The whole reason I got into this is because I wanted to fix my save game which i screwed up. I've mostly done that now, although I found I could change the number of points I had in anything but I had trouble changing the number of talents my character has (I wanted to remove one that I got in error.) It seems like there's more than one variable keeping track of the number of talents each character has perhaps? Idk. I will upload my code to github soon and post a link here though (it's very basic, command line, no UI). Thanks for all your help.
