The marble thing is happening to my friend on my unlisted completely vanilla server. She hasn't tried playing in SP since it started and it only first started happening in 19. She recently did a file clean, so we'll see if that helps. If not *I'll* do a file clean and see if it helps. I know this is a relatively stale post, and I'll continue reading through the rest of the thread and see if there's been any new info since last month.
