I would like to check out the early builds of the game again at some point. The last time I did this (.70b3) the contents of my mailbox disappeared even tho I started a new game and didn't touch the mailbox.  Would it be safer to bring all the items to my current 0.9C save before going back? If I lose my plushies again its no big deal. It'll just give me something to do and stay outside the base more. Right now I wanna see what happens when a save is brought to the 999th day while running at 2X day speed. No spoilers, please.
