Troops attacking non front line team members?

Had a damaged Giant spider in firsrt slot, empty slot, and then my hero.
He had a Bandit in first slot. Matched skulls, bandit animation attacked my hero killing it, damage spider still in first slot.

Same game.
Egg Thief with no status effects on it. 22 armor and 57 life. Bandit (40 attack) matches one skull triple - no other skull matches, no doom skulls, no rage, etc. Hits the Egg Thief and kills it.

Seeing lots of weirdness recently - 5 matches where only 3 in the middle match and no extra turn, etc.
Wonder if they screwed up the timing engine again.

If you believe that this is a bug, you need to post in a proper section.
