This script will only work if you have the following mods installed:

• CraftTweaker
• Iron Chests

This script allows you to do the following:

• Keep the central material you're upgrading from when crafting in-world chest upgrades, thus costing the same as upgrading the chests directly within the crafting menu.

NOTE 1: Now requires a diamond for the crystal and obsidian upgrades instead of obsidian and glass respectively.

Simply place the script or zip file in the "scripts" folder (located in the same directory as your "mods" folder).
