Anyone ever come across anything like this before? My chain lightning spell just stopped working, but only in my right hand, thunderbolt works still, but chain lightning doesn't work in my right hand.

Luckily I had an autosave just a few minutes beforehand, but the cause of the problem is unknown so if it is caused by something before than save and just takes a bit to take effect, im in some trouble.

So, anyone came across anything like this? I found one link through google but there were no responses to the topic.
