Online bug

The person who joins the game experiences a lot of bugs: monsters move in slow motion, players get teleported, blocks break slowly, and damage or hits happen randomly. It doesn’t matter who is hosting—the invited player always ends up bugging, even though they have a good internet connection and the exact same game version. Whether the Switch is docked or not makes no difference. The game has been reinstalled, the Switch has been reset, the connection restarted, and both the console and game are up to date—yet the issue remains.
