Someone knows how to fix this error of the slabs, when the player passes on it gives a bug in the console "moved wrongly!", Already thanks ..
player: #Choose whether to enable player data saving. save-player-data: true anti-cheat: #If false, will try to prevent speed and noclip cheats. May cause movement issues with some blocks which are not yet properly implemented. allow-movement-cheats: false (change to true)
