[GAMEPLAY] Two games with the same players at the same time

Hi there, i just played a game with a friend of mine. At the beginning everything looked like it normally looks like but 1 minute in the game everyone (not only my friend and me got into the loading screen again) after the loading screen was gone i could switch between the two games. A part of my team played the game 1 i played game 2. THen i had a DC and from there on i coulndt switch between the two games anymore but played game 2 to the end. Logging onto my account right now still say i have to reconnect anyways... But when i press reconnect the game just crashes every time.
