Have you had any issues (i.e., bugs) with "leveling up" getting stuck? My issue at present is with stealth, but it's not the first time I've had this problem.
My bow skills were stuck at some level for a long time.... I used the bow almost exclusively, killed more creatures than I could count, and there was no change in my bow skills level. The way that I broke this cycle was that I "trained" bow skills up at the crags -- and it seemed like like once I'd "pushed" my skills with training, I was then able to advance levels normally again.
The other area in which my level is clearly "stuck" is in stealth. I hide almost constantly. My bow skills are at 160, my sword skills are right around there -- and my overall level is around 30 -- but my stealth has been stuck FOR WEEKS at 23. Given how much sneaking/killing I've done over this time, it's clearly a bug. It's wrecking my enjoyment of this game.
(1) Any suggestions about the bug in general -- and anyone else who's had similar issues?
(2) I can't remember: is there anywhere that I can train in stealth...? If I could train, I feel like it might be a workaround (the same as it was for my stuck bow skills), but I can't remember whether I've seen any stealth trainers...?
