At some point I caught something, and I'm not sure what it was. While looking at my skills, I noticed that only my "one handed" skill was decreased by 10. Which was bad since I was using a one handed weapon. That was the only skill efftected, and the number was showing up red in the skills screen. So I searched all through the menus to try and find out what was wrong with me. After I exhausted every part of the menu system, I never found any place stating what negative effect I had on me to lower my one handed skill by 10 points. I even tried just drinking a cure disease potion just to see if it would cure it. But nope, didn't work.
After a while, not sure exactly how long, but it seemed like a long time, it had somehow cured itself and I was better with my one handed skill back up to where it should have been. Anyone else experience something similar? And know where to look to see negative effects like this? I was in the menu for magic where I thought ALL negative effects should have been listed, but it only listed a couple good effects I had on.
