Major - High ping causes player jittering (happens mostly on consoles)

Even if you set a BP prop to movable, the player will jitter on it if the prop has been rotated with a level sequence first. This is how it looks:

1) Attach a lot of BP props to an anchor
2) Rotate the anchor with a level sequence
3) Play on high ping and step on them
4) You cant jump anymore and the player stutters, you can only move

EDIT: Seems its the bottom of the map, just outside the island borders that is causing it.
