Why would you suggest this, when it has nothing to do with the issue at hand, and costs money? That is not what the OP wanted.

TBH, it's a valid option. They switch sharing save files back and forth so that someone else can host while someone is offline, and a hosted dedicated server would certainly solve the issue of save files getting lost in all that mess.
