Unexplained Stat loss

Ok, for some reason when I leveled up to level 20 I noticed that my Dex and Con had both dropped by one. This kind of sucked because I wanted to increase my melee skill but now my dex is to olow, so Ill have to spend my hard earned point on a dex point I ALREADY BOUGHT.

Now what really p*sses me off is that there is no explanation for this loss. Im not poisoned. I have no cursed items equipped (I even went so far as dropping absolutly every item I was carrying and wielding) so its not Encumberance either. I checked the log book. I have no curses or injuries that could explain this. Im really angry about it. Ive put about 20 hours into my character so far and now I have waste two character points on stats I already bought! :x

 

I would think it's a injury but since it ain't my choice would be bug.

 

Aggghh! When am I going to learn not to just rely on quick-save?

I patched to the latest version too. I guess a bug slipped through!!



(Im in the Tarant sewers BTW and I know it isnt that cursed sword because I NEVER equip unidentified items)
