Seamless Travel not working when clients connected (UE 5.4.2)

Hey,
So me and a team of my friends are trying to make a multiplayer Lethal Company-like game and when switching levels from the lobby to the level (with a transition level in-between), it only works when it’s just the host in the game.

After reviewing logs, we see this error:

[2024.07.14-18.38.42:900][477]LogNetPackageMap: Error: GetObjectFromNetGUID: Failed to find outer. FullNetGUIDPath: [7]/Game/87KGames/Levels/Lobby/LobbyIsland.[5]LobbyIsland

and also

[2024.07.14-19.50.44:706][451]LogLevel: Warning: Failed to find streaming level object associated with '/Game/87KGames/Levels/Playable/Eastside/EastsideFacilityLevel'
[2024.07.14-19.50.44:693][450]LogLevel: Warning: Failed to find streaming level object associated with '/Game/87KGames/Levels/Lobby/LobbyIsland'

Here’s the blueprinting below:

We genuinely don’t know how to fix this, so any help is appreciated!

Cheers :slight_smile:
