server 27018???

This game session is no longer available What the...???

I saw that once too.
It seems to happen if you connect and the map is changing in the same moment.

The session is reserved it seems.
Dont know how they did that.
Normally it should be unreserved automatically.

I could unreserve it manually now.
Dont know how this is possible.

hacker attack or gremlins

They are steam players.
I think they even did not know how this happened.

Happened again with other players.
Dont know what is wrong there.

It seems that connects from lobby are reserved.
With my steam client I can connect.
RevEmu client get that error message:

Disconnected
The session is no longer available.

It seems that the plugin unreserves when 4 player are connected.
But not before.
Strange that I never saw that before.

I had the same issue many times when i tried to connect through my recent servers history, after a !votemap or after a game crash..sometimes i connected to some strange servers (especially Versus servers  )
No problems when i'm connecting using server's IP in console though:!:
