Randomly my skill in Archery will drop to 15.

I don't have any diseases listed, and I've drank hundreds of cure disease potions just in case. The quickest fix for this issue is to simply go to a skill trainer and train the skill, and that returns it to normal.

Several other people have noted this happening with One handed too.

To note: None of my gear is causing damage to my skill (I sat there naked) and I wasn't debuffed (I waited 1 week in game time, in my house, and slept.)

Not sure what causes it, but I figured I'd post it here. (Btw - the skill isn't lowered, just damaged. My skill is the same as it has always been, but it shows 15 in red, meaning I only have the efficiency of lv. 15 archery unless I train that skill.)

Had the same problem with one handed. I wasn`t diseased but poisoned. So took a cure poison and everything went back to normal.

Ok but where do you find a cure poison potion? Seems no alchemical ingredient do it nor merchant sells it. So where?

I have the same problem and I know I'm not the only one. I think it's a glitch. Usaly leveling up or increasing the skill will take care of the problem.
