My matches goes to CPU's pool...

In Black Widow PvP, just 10 mins ago…

My team - Black Widow, 166 Thor, 166 Hood

CPU Team - 200’s Black Widow, 166 Thor, 166 Hood

My turn - I have 10 greens and CPU have 10 greens… I am watching carefully for greens as I do not want CPU to cast Call to Storm on me…

I three matched greens…

End of my turn - I have 10 greens STILL and CPU have 13 greens

CPU’s turn - Hood Stole one Green and CPU cast Call to Storm

I lose the match…

Why did the three greens goes to CPU’s pool instead of mine? (I make the match)

Is it a bug or a feature to encourage us to buy health packs?
