Join session loads wrong level

Hey all,
i got a weird problem: When i try to join my session via network (Play Standalone Game, Play as listen server) the client loads the main menu level instead of the lobby-level. However if i join my session with the same device it works perfectly fine.

What i tried until now:

  • added “listen” as an option on “Open level” node
  • added all Maps to packaging
  • added all maps on the asset manager
  • double checked the map directories

If I try to run it in editor window I i get an error:
“TravelFailure: LoadMapFailure, Reason for Failure: ‘Failed to load package ‘/Game/RTS_Project/Maps/UEDPIE_0_Lobby’’. Shutting down PIE.”

  1. Why is Unreal renaming the map?
  2. Why does the client load the wrong level?

If i try to package the project i get an error:
ExitCode=25 (Error_UnknownCookFailure)

I someone has an idea I would be really happy because i cant test my lobby behavior over network right now and I dont know what else I could do :frowning:
Like stated above joining my lobby with a second editor window on one PC/laptop works perfectly fine, just joining my PC lobby with my laptop (or vice versa) shows this weird behavior.

Best regards,

Closing this because i now use PIE
