I also have a problem with the new versions of ViaVersion and ViaRewind. Version 1.8.9, sometimes players are not displayed or blocks that the player did not put are displayed. I tried to roll back the plugins to version 4.0.1 and everything was OK with it. But the plugin version 4.0.1 does not suit me, I need to use the new version. I think this problem is similar to the one above
