[2020] One player cannot play the gamesave of another.

People will eventually want to trade game-saves at some point so they can play under different conditions or even just try out different combinations of islands (I was trying to do something similar to that when Lord-Xanthor and I found this). Right now, the land won’t load, the tools won’t load and the coin balance resets when you give someone else your game-save (we tried with multiple saves just to make sure). Perhaps we should change it to the game-save won’t load if there isn’t a valid beta key? not sure how we would do that, but (as with most games) players will eventually want to trade saves, so fixing it now would save us from doing it under time constraints when people start asking. Marked as a new bug because it is a problem that needs fixing,not an improvement to be added.
