I was playing on my Windows 10 laptop with a super flat world full of blue ice. I was just screwing around with a boat and went pretty far out. I suddenly hit an unloaded chunk. I was expecting it to just load with a bit of wait, but instead I had the chunks stay like that. I tried to get out of my boat, but the game just started to move my camera back and forth several times a second and leave my player uncontrollable. 

I would provide an attachment but the file is too large.
