Talents Reset Mid Fight
I was fighting Wisps with my friend @LilCassiopeia and my talent tree reset on me mid battle. I suddenly ran out of mana and it was regenerating so slowly, due to me initially not being a mage build, thus making my character completely useless for the rest of the fight. What makes it even weirder though, is that i still had all my skills to utilise. They didn't disappear.
Fixed in v.a.2.3.3o
