The server is the one who saves and loads
When u enter the level a loading screen appears, 1 second is delayed just to make sure every player is in, if player is server then it will load and with a delay of 0,2 seconds to make sure its loaded, it will save again. then the last 0,3 seconds are just for aesthetics.
Ik, just added it to make it easier to “access” but it does the same as the ue5 default booleans
