I used a cheat to get more dragon souls and now im like -23837583 souls. I dont know how to fix it. I tried adding more, but it has no effect. The cheat i use was "player.modav dragonsouls ###".

Reload an earlier save.

Know that misuse of the console and its commands may not bode well.

Here's a question for you... I killed a Frost Dragon [now I've reloaded and killed this dragon 6 times with no change] and I can not absorb its soul. I tried to use player.setav dragonsouls 1 and it does not work. Do I have to reload an earlier save, ignore the dragon, and come back later to try to get the soul and the word? [this is Bonestrewn Crest, am I not getting the soul because it's a bounty I haven't taken yet?]

Secondly... is the console not working for that because I play with Steam offline?
