Did I just gain permanent 30 mana?
 

I noticed my warrior's mana is at 62, whereas it was 32 some 1 RL hour ago. What could cause this?

EDIT and it just happened again - my mana jumped to 92 now. I suspect its the mana acceleration mod, which degens rage and regens mana as if you waited. Any way I can edit this?

EDIT#2: 122 mana. Without the mod. How do I reverse this?

EDIT#3 I found out that I can restore my mana back to 32 by using the cheat console. Will using a cheat a repair the bug affect my final score in any way?

It's a bug, and people have reported it even without using the mod.

Not sure about the sure, I would think a cheat command does affect it.
