Ok everyone, I've done some testing this morning (many apologies to llamabeast for spamming his server with fake games

) and it appears the Alexander map has vanished. As I tried starting games with 3 different version of it, and all went up in smoke the moment I started them. (but then I tried starting a game with the recently added Land of Legends map as well, and that also vanished when I started it. But another game recently started using it with (it seems) no problems. Just odd all round basically ?!?!)
But I just tried starting a game with the Asia Twist map, and that started just fine.
So my next course of action is to try re-uploading our version of the Alexander map, and the original version, and then trying to create games with those two maps. If that works, then we should be good to go for another start attempt. If it fails, then I guess other than waiting for llama (which I never like doing as he's a busy guy, and I like to see people trying to solve their own problems first), we will just have to go for the Asia Twist map that is already on the server. It apparantly has fixed starts for 16+3.
Will keep you all informed of my progress as best I can.
