I've run into a bizarre problem in Arcanum: One of my spent skill points (in Pickpocket) has disappeared. As I am unsure of the why and the how, I figured I would bring it here.
After noticing the problem, I flicked back a few saves until I found a save where I still had the skill point. Unfortunately, this is relatively far back, and I don't really want to have to do all of the things I have done in the meantime again. (I keep a lot of saves, but I save over older ones as I go along.)
I pondered over the skill loss, and wondered if it might be a feature of the game regarding skill degradation. However, I disregarded this as silly and instead questioned whether it had something to do with the fact that it was my only skill that I had not received training for so far (I've been looking for a trainer - maybe the fact that I no longer have the skill point is why I can't find one). Another thing that puzzled me was why Pickpocket acts as though it were a slowed growth skill - I am a half-elf with the Charlatan's Protege background, and all of the other skills I have act in accordance with that, though I received no explanation for Pickpocket's stunted growth.
Is there some way I can fix this besides reloading my old savegame, or will I have to deal with the mysterious loss of one of my skill points?

Thank you - I think that must have been the solution, as it restored Pickpocket to a normal-level skill rather than a stunted skill in the save I had before the skill point disappeared. It must have just been that I'd bought some new gauntlets which burned away all of my Pickpocket skill - at any rate, I'd decided to load rather than face the possibly of having lost a skill point, and just went around redoing some quests.
