Now, I was in a strange position. I was on the server at the time, but I was the ONLY one not suffering from said problems. What occured was:
At the end of a round, everyone seemed to lose their connection, or suffer a map change, and then the game reloaded ns_eclipse, which was the map we were on. (Excluding me.)
Then, as expected, everyone reconnected. After a few moments, the round restarted. Then, to my suprise, the majority of both teams AGAIN disconnected....only to return in a few moments (At this point, Kodiak, behind me, was getting frustrated and being angry at his computer). This continued to occur, with people connecting, disconnecting, and then reconnecting. I heard that some got certain admin or server messages as to the cause. However, being not directly affected, I cannot tell you more. Simply a witness.
