Thanks !
I couldn’t warn the gamemode because I was a mad bug victim lol. I load the sublevel from the main map. It warns the controller so it can display the loading widget. No Problem here. But when I created a “execute on server” event then tried to call it : “nope I refuse ! :p” . lol Every time the input had a “new boolea” name and made error. I could create it, compile then try to call it… it didn’t work. So I couldn’t et the variable on the server and read it from the gamemode.
Today (I’m in France), I tried to insist : creating the event, compiling, adding the bool input, compile, call it in the function, compile. Rince, repeat as fast as possible and MAGIC at some point it worked ! :eek:
Now I have a new problem lol. This seems to work fine
After the branch, I load all the necessary things, spawn the character and make the controller possess it.
But when I test and ask for 2 players as clients and hit Play, The first one never triggers this (never gets a character) and the second player gets a character that… falls into the ground… 
Unreal, you hate me. I don’t know why, but you are mean ! :mad:
