TF2 Classic has many known bugs. We're aiming on patching these for next release: Teleporters can't be spawned. Spy's disguise can often break. Software cursor can cause issues on some clients Linux (client) isn't working (see here) Joining spectator in DM says you've entered the battle. Opening the scoreboard on the MOTD causes you to be stuck. If your bug is already on this list please do not bother creating a new thread for it. Thanks.
