The mod tries strangely hard to retrieve the list of donators, enough to the point where it waits 1-2 minutes between attempts before giving up, and sometimes still will start a new attempt. If the website is down or the mod experiences any other sort of connection issues, the game can take as long as 5 minutes or more to start up.
