When all party members die and leave the dungeon, players can still use the /back command to return to the dungeon and break blocks.

About 90% of servers provide this command to players, so disabling it is not a good option.

I have already set PreventTeleportIn: true, but it does not work.

This issue only occurs in single-world dungeon mode. If OneWorldDungeons is set to false, the problem does not occur. [Legacy attachment omitted] [Legacy attachment omitted]
