Vortex Wars

Hello i keep getting to points when i cant see my frineds in lobby so i gotta click join on social screen, but then the peep who were in lobby first goes away. It like its more than one lobby.

the same thing happoned to me. i see some of my friends in the lobby when i join. then go to the socical screen and join 1 of my friends (what is not in the lobby what i can see). then i join him and there is different people and cant see the friends what i could see before this.
