'Connection to your opponent has been lost' as you know yes.. That's how in other words you've been kicked if there is an admin activity..
I got kicked 5-10 times everytime I kill a DHS clan member... At first I thought it was the connection but it seems to happen everytime I kill one of the members.

PS: I found a reloading trick, it's not a bug, it's there in many games.
PPS: I'll make a video about it to show what I mean.

Thats really annoying. So y dont now what goiing on.

Can admins give a comment on this issue ???

It happens to me a lot on my own servers since the recent "Gamespy Maintenance". It probably isn't the server... You can do that to a player, but its a pain and a minority of server providers even support the required level of access.
