Just an update, if the battle was close and there are only a small percentage of survivors, that set of cheer animations plays and nothing freezes, it is only when the enemy was defeated easily, or with moderate ease. Also I think it’s only the crouching animation as seen in the video above, and one other one where the character stands straight and raises their weapon hand(right hand) up slightly, like a lazy raising of the weapon, not fully extended arm, like a chopping motion. Hope this helps, if I notice anything else I’ll be sure to report it.
