What you were expecting to happen, and what actually happened
I was trying to win a PvP battle and get rewards from a gnome but what actually happened is the gnome took damage, but stayed in play instead of dying, I proceeded to win the battle as normal, but received no rewards from it. In normal cases the unit stays in play and I win and get rewarded as intended.
How often does this happen? When did it begin happening?
It can happen randomly with any unit, normally it happens so quick I am unable to capture screen shots of this happening, but this time I was fortunately able too.
Steps to make it happen again
Play any game mode that involves combat - Although it happens most often in PvP.
