So I recently got the ability to use Hold, and I've found that in the park (I haven't tested in the home or a match) that sometimes when holding a structure such that my arms DO NOT make a pose, the structure will break the hold and fly very fast into me, or behind me, similar to a straight, but without the sound/visual effects or knockback. This seems to happen significantly more frequently when holding a ball. It also happens if I move my holding hand out of my sightline SLOWLY and without making poses.

In the gif added, I failed to recreate the ball flying into me because it didn't have enough speed to break the hold. roughly 2 seconds before it accelerates down, my hands seem to be at my waist for 1 frame, like in the image. While the ball accelerates down, I am not performing a pose (to my knowledge), and especially not one that would influence the ball's motion like that.

Edit: I should mention this because it might be useful

This bug has happened less and less with every time I've loaded the game; it happened non-stop when I first unlocked Hold, and has happened less per session since then. It may also be connected to being client in the park; it happened frequently the other day while I was on client, rather than host. (However it still happens when host)
