Forum:Damaged skills

While playing New Vegas, I noticed that several of my stats (medicine, survival, and sneak) are damaged. They show up as 0 with a - next to them. I've played Fallout for a long time and know things like addiction and injury can damage stats; however, I have ensured this is not the case. I even tried sleeping in a bed for 5 days in a row and taking Fixer, eating, and using a doctors bag- all the stats are still 0.

So I went into the console and tried both the player.setav and modpcs cheats. No matter what I set it to, all stats stay at 0. If I set them to -20, the - disappears and they show at 0, but anything above reverts them to -0. I've also tried forcing a level up, at which it displays the medicine skill at 67, but increasing it still keeps it at -0.

If I go back several savegames (about a weeks worth) the skills are all normal; it's around the time I go into the Hidden Valley that they revert, although the presence of the slave collar doesn't seem to make a difference.

Any ideas?

Update: By going back in my savegames, I found that this occured when moving into the room right before Mortimer gave his speech at the Ultra-Luxe (1 minute between a good save and one with the damaged stats). I also removed every single mod I have installed from the game, and tried to edit it again, but still the same issue, so it doesn't seem to be mod related.

Update 2: Finally narrowed it down to the "More Perks" mod. I added the perk "Destiny Gambler" and then ditched the dice apparently after I got a penalty, and so it never reverted. I downloaded the most recent version and they provided a fix, all taken care of!
