Battlegrounds Bug - Mega-Windfury didn't Work

In Battlegrounds, my “Golden Zapp Slywick” (which says Mega-Windfury) couldn’t kill “Elistra the Immortal” because it only attacked twice, and was still alive after attacking, only twice.

The game was close, and I would like to say that I would have come first, instead of second, but who really knows. Anyway, I just wanted to post my bug report.
