i have been stuck on level 4 for a very long time now. and i slept and so on..but it wont go to level 5.!! you the progress is not goin up..and all my skill are just about full...do they have to be all the way full before you can go up to the next leve???
Hmm... That sounds very strange. Sounds like the sliders have frozen somehow. It's easy to see if the sliders are moving or not. Just try summoning skeletons a few times. Skill increase is very quick if your conjuration skill is low. You only have to summit it 5-6 times before you gain a skill point.
I have no idea what could be wrong here, but a mod could cause this I guess.
