HAAT after topple doesn't trigger?(P4)?

Yes I can say its definitely when someone dies that causes it to not drop b2's

It’s been that way from the beginning. My experience seems to be that it happens after somebody dies, but I haven’t studied it carefully.

Yes it does randomly break. But I've never noticed a pattern to what causes it to break.

From my experience it happens after somebody dies before it’s toppled, then once it’s toppled and goes back to normal it just takes pity on you because you’re one character down.

7* zombie, HAAT killer.
