Unreal crashing after moving files

Hey Get_DOVAH_it!

Thanks for your quick response! I found no easy fix unfortunately. So i ended up rebuilding my whole project fixing all references. It looks fine so far the only thing bugging me out:
I cannot get the second player controller. Get player controller always returns “PlayerController” not matter where i call it (in Widgets, Playercontroller, Playerstate). However the Gamemode PostLogin node returns me PlayerController and Playercontroller1 (as it should be). Does anyone know how i can get both player controllers?
Also weird: “Get owning controller” in playerstate returns:
On server:
Playercontroller for Playerstate
Playercontroller1 for Playerstate1

On client:
Playercontroller for Playerstate
Noone for Playerstate1

How does the client knows about the controller of the server but not his own owning controller?

Also my save-game folder appears to be empty but i can data from slot:

How does ue4 load data from an empty file? Has the location of the savegames changed?

Best regards!
