I think it happens more often when there are >20 players. If there is only few of players for example 6 players, It can exit to lobby more often. Yesterday night, there are >50 players, that freezing occurs almost every times in Battle_CN server. But today afternoon, I found that if there are 5 ~ 6 players, it can exit to lobby. But that issue still exist today, I joined the server about 10 times, there are about 3 times that game freeze occur. (~20 players when that occurs). I am also not sure whether the game freeze is related to unit we choose, I remembered that those players are using infantry when the game is not freeze.... Also, I am not the only one have that issue, many of us have this issue too.
