Monster Dies and Mana Depleted at same time...no credit for defeating monster
This happens to me EVERY day.
Just because you can not recreate it does not mean it does not happen, If I go into battle and the monster still has 60% to my 100%, I KNOWit will happen.
The mana runs out just as the monster is defeated, but no reward....see photo. I can send you a new photo each day that it happens if you wish.
