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
