When I get out of a boat.. it goes glitches away. I can walk over it.. but it glitches me around and I move as slow as cobweb. I can,t break or place blocks in the boat, nor see it if I turn on hitboxes. If I reload the chunks, textures, or world it doesn't go away!
I recorded it on video.. here is a link to Google Drive File https://drive.google.com/open?id=1pAyGf4evEeS5uwJ8wjgBAEZ7wVLgCyag
