Today, I log my sorc and here is the number I found :
This is a vampire bug, because when I curse vampire, here is the number :
There is no 10% difference at all.
I lost about 200 magicka regen, and there is only a few point without vampire.
I've 25% magicka regen, I'm altmer, and I use 2 magicka gold regen glyph + a classical gold bonus regen set from Magnus.
How I lost 200 regen ? How 10% difference is not the right number.

Pls zenimax, fix it for the live
