Freeze Tag Servers
I don't think this has been reported yet. I don't know if it happens on other freeze tag servers but the ones in Europe (DE and UK) are crashing randomly after a game ends.
I haven't been able to find out the reasons that cause it, it only happens sometimes.
I've seen it happen on both servers, several times in the last week.
So basically that's it, the game ends, the scores are shown and the server goes down.
The next time it happens, Alt-Enter to go in windowed mode and retrieve the server link. Give it to support (firstname.lastname@example.org) along, ideally, with a demo of the match. You can also PM sponge on IRC instead.
