Character Sliding across grids
Just about a year ago I experienced a bug like this - I havent had it for a few weeks now (started playing again a few weeks ago), though today I experienced it happening again, I can't move forward when it comes to sloped blocks, and when I land on a horizontal flat plane I keep sliding towards the direction which I was moving in before I landed.
The character will keep sliding until he lands on flat ground on a planet or hit another grid.
This is grid specific, so I can walk up onto another grid and not have this issue, while the issue persist on where it first happend.
The only thing that fixes this, temporarily mind you, is restarting/reloading the server/map.
This happens both in singleplayer and multiplayer, both dedicated and locally hosted multiplayer sessions.
I provided a link below to my original post a year ago - since its still relevant to this day.
If you need a newer version of a map then let me know.
