Title. Only about 25% of the time does my group actually stay in the group.
Yeh i gotta say this was the most annoying thing for me in the Beta. Group never stayed together when exiting back to the lobby.
This problem continued into the 2nd day of the Beta. It actually got worse because invites started to fail regularly on the 2nd day. The odd one might require a 2nd invite on the first day, but on the 2nd day every time we tried to reform the group, it would require sending the invite 5 or 6 times.
This bug seemed to be introduced in one of the hotfixes they did on saturday.
On friday i was leaving with my group on post match screens and it worked fine every time, then there was a downtime around midday on saturday (GMT UK time), after it was back up, all of a sudden i could no longer take the group with me, we had to continually reform the group.
