When I walk around I glitch back a couple of blocks. I logged out and logged back in and it still did that. Then I went onto another server
to see if it was happening there to, but it wasn't. I don't know if it's my computer, it doesn't seem like it is, but I thought it was worth mentioning.
If anyone else is having the same problem, just comment or reply below about it below.
I will try to fix this on my own, but if it could be looked into that would be great.
