ICO's last crash
FYI, we just hosted a big game with the host having Alloy on, and it immediatly locked up and ICO crashed again until someone reset it. I just hosted a game after having everyone turn Alloy off, and we seem to be fine. Just providing feed back for your troubleshooting. Might have been a coincidence, but it seems possible that the host site is not friendly to Alloy?
Good Luck
