I seem to be hearing and noticing problems with coldsteel. I know the server crashed once when we had tried playing it. That was a couple of weeks ago. I think that was the day I went in as admin and forced a re-load of that map, and then it worked. (we didn't want to play torlan.)
I'll have a look see and see if I can spot anything with the map itself that may be contributing to the problem if I don't forget.
