Raikou Lightning Rondo Bug

Zoxus

I used Lightning Rondo with Raikou to take a knockout with 2 full benches of 5 pokemon, and the Raikou remained hovering over the board. No timer appeared, but Raikou remained hovering over the board and not resolving the attack until turn passed to my opponent, who continued play as if I had timed out and my Raikou was still floating in attack animation.
