How to Update to Mighty Mail 1.1 and above:

As of version 1.1, a breaking change was introduced in order to fix a compatibility issue when installing the mod with MrCrayfish's Furniture Mod: Refurbished. Unfortunately this update will delete all registered mailboxes (the mailbox blocks will remain in the world, they just won't show up in the post box interface). In order to avoid this problem, a simple fix an be applied.

This tutorial is based on Windows, directories may be different on other operating systems

1. Locate your saves directory. This can be found inside %appdata%/.minecraft/saves or your custom directory defined in your launcher profile.
2. Open the directory of the world that you are playing, and then open the data directory inside it.
3. Rename the file refurbished_furniture_delivery_service.dat to mighty_mail_delivery_service.dat. If mighty_mail_delivery_service.dat already exists because you updated to Mighty Mail 1.1, override the file when prompted.
4. Profit! You can now play with Mighty Mail 1.1 without your mailboxes disappearing.
5. Apply and repeat the steps to other world saves you are playing.

If you would like, you can delete refurbished_furniture_delivery_service.dat. However if you install MrCrayfish's Furniture Mod: Refurbished, the file will be generated again and you should not delete it as that contains the data for the mailboxes in that mod.
