Been playing a few months and I have a few Toons, I was leveling them after the upgrade, and got to a point with kill the flamebringer. OK so I tried it a few times ans then i noticed a link in the guide thing that said rescue maria, so i did and it went through new screens. And when i looked into my hero in formation she was in there as a sixth toon

I was like kool six guys, but no i would go into battle she would be there but when the battle began she would disappear so i just used her to replace a toon and that worked she actually healed me enough to beat the flame bringer NPC then after i went to lexi and she said she was home and she was gone. but this char really made the game fun for one minute and it is what this game needs in my opinion we need a healer toon like maria
But the bummer is i have not been able to recreate this event in any of my other accounts and I'm stuck on the same monster. So has any one else had this event happen?
