Mana regen gets stuck.
 

I know it's an old bug that mana and health bars have a problem with reporting, they go something like 30% , 35% then 32%, while sitting.

But I am seeing something else.

Mainly I notice it with mana because I am being healed up to full anyway.

With mana I see something like, 50% 53% 50% 53% 50% and so on.

I have to stand, normally move a bit and sit back down, then I regen again.

It's not often that this happens, think it was only twice last night over a period of 6 hours.
