Seems that somehow my character has been imparted with a permanent +3 agility bonus as a result of cashing in dirty and regular pre-war outfits to the SM vending machines. I suppose I was wearing them at the time or something, and the game removed the item from my inventory, but did not remove the bonus from my status effects. It must have happened 3 times, since I currently have a +3 agility bonus.
I play on PC, so an effective console command would be helpful.

Thanks.

I would make a fresh save before doing that, as applying negative shifts to skill or SPECIAL values can crash the game.

I would also recommend making said save right after using an auto-save point (such as a zone door), as there's a chance, albeit fairly low, of said crash totaling the save in the process (I had this happen in FO3 during a test, fortunately I had just left Megaton).

Thought about it, but while that lowers my ability score, it doesn't remove the status effect message. Thank you, though.

At this point I just relaoded my pre-Dead Money save and started over (*sigh*). At least now I know better.

Hey, this really works! :vaultboy:

Um, bad designers! Bad! :sadvaultboy:
