With the release of Minecraft 1.13, the storage format has been changed significantly, this results in lost items if a backpack created with an older version is opened with MC 1.13 (or newer).
This page will describe you how to properly upgrade your backpacks to the new format.
Requirements:
- Minepacks V1.18 or newer (but not V2.x)
- Bukkit/Spigot for MC 1.12.2 or older (only fully tested with 1.12.2)
Steps (Minepacks V1.18):
- Backup you database!!!
- Start your server
- Use the "/backpack rewrite" command (Permission: backpack.rewrite). The plugin will not be usable while the command is running. Depending on the amount of backpacks it might take some time to complete.
- Wait till it's done
- Stop the server
- Update to MC 1.13 or newer
Steps (Minepacks V1.19):
- Start your server
- Wait till the plugin is fully loaded
- Stop the server
- Update to MC 1.13 or newer
