Ok so this happened 3 times to me today, a person leaves and another person drops from the game like at the same time. Happens in different games and no one was hacking.

Do you have replays?

Isn't this just the ol' Lat thing...

basically, in a super laggy situation

the only way that one person's connecting with another is through a third person

A -> C <- B ... probably because A or B has port/firewall problems

so when person C leaves, the connection breaks.

Yeah, it has to be connection issues.

There wasn't any lag actually...
