Sorry, I never found a good solution… Since nobody answered me, I found a “bad” solution. I have added a delay node before calling the run on owning client event in the “on possess” event. And since I have also seen that it could take some seconds, I decided to have a delay of 5s.
If we think about it, 5s to launch a game is nothing, so it is not a big deal, but how to be sure it will never take more than 5s ? We can’t…
Sorry, it is the only solution I have found, and I agree it is quite ugly…
If someday you find a real solution, please tell me
