For some odd reason, even though I have absolutely no conditions affecting my characters, they seem to be suffering from reduced stamina and HP. I tried removing all my mods, checking (double and triple checking) to see if I have any sort of condition, etc. The HP on one of my characters is reduced by 15 and the stamina for a different character is reduced by 50. Does anyone have any idea what's wrong?

My stamina was reduced by a fair amount once, but I can't remember the cause. It might have been an enchanted item or armour, or a disease.
