!!!!!! EPIC GAMES MULTIPLAYER PROBLEM

Hello.
I have a problem with the EpicGames platform. In "Mudrunner" I cannot join an existing game. I was playing with my friends and it was not possible to invite friends to a saved game. Everyone played as if on their host. You can only invite friends to a new multiplayer game, but then progress is lost. I contacted EpicGames but they said the problem was with FocusStudio.
On Steam, it is possible to invite multiplayer from the steam overlay but EpicGames does not. Please fix this

Thanks for the feedback, we're looking into this issue.
