No, I have no disease. I cured any poisons. Nothing in the active effects has a negative impact. I wear plain Daedric armor, no enchantments. My One-Handed is supposed to be level 90, but for some reason on the skill screen it shows up as a red 20.
It's very awkward and I don't know what to do.
I had to do a 'search' on the tips forum for this today- I dropped 50 in 2H, no active effects on me
I leveled up the skill, it went away
I think it's actually just the displayed number is shown wrong. if you enter the tree for the perk, your real skill is till listed
