I don’t want to comment on the volume of disconnects from host, other than say they seem more frequent than any other game I currently play or in memory have played.
IF FS can’t do anything about them, fair enough. But it is inconceivable that you haven’t thought about the time and energy spent by players on lengthy chaos waste runs, only to then be disconnected on the final battle. Boom 45 mins gone with absolutely no reward.
Why can’t you award vaults based on progress at the point of disconnection? Is that really too much to expect?
