I have no diseases (used a shrine multiple times) and I took all the gear off my character but my one handed skill shows up as red and is lvl 20, when it is actually lvl 50. There is nothing in my active effects that says why this is happening either. Anyone know?

I had the same thing all you have to do incr the skill one more time and it will be normal and since you cure it it does not effect the skill really its just a visually bug

edit do a save and visit a trainer and paid for it and see if changes back to normal for you I know it work for me.
