I completed all the Winterhold College quests so I could get the Arch mage robes and the Morieki mask witch both make magicka regen 100% faster. My magicka regenerates like crazy fast, but when I have them both equipped my you can't see the mask or even my characters head at all. Just an empty hood. It looks kinda cool at first. But it is really irritating me now. Any body else have this problem?

I've heard and seen it before but I havn't experienced this myself. There have not been any patches for it (As far as I know), so you'll have to deal with it for a while.

I'm fairly certain you're not supposed to be able to equip head gear with that robe so I think if it is patched the, the feature would be removed.
Also if you try it a fair number of times the mask will fit over the robe.
