Huge Update. Turns out there was an error with the game, where the game will use the save file from FNaM 3 Classic. So, read this post carefully

If you started the game and repaired maggie in the first repair section, is not necessary to download this update. I would STILL recommend you to download this update to avoid any conflicts in the future, but is not entirely necessary.

If you do download it, all your data will reset. To fix this, start the game, wait for the repair section to appear, close the game, and then do the following:

-Search on your search bar "%appdata%"

-Find the folder called "MMFApplications"

-Open both files called "Maggies3" and "FNaM3" with notepad

-Copy everything from "Maggies3" to "FNaM3"

-Save it, and open the game

Your data should be restored

If you started the game, and in the starting repair section you DIND'T see Maggie, then you don't have to do anything, BUT the game will reset completely. So, download this update only if you experienced this error.
