ItemCoreX 1.4 - Major Custom Item Update

Added:

  • True 1:1 custom item saving
  • Custom items now keep their original name, lore, enchantments, attributes and flags
  • Custom stack-size support for ItemCoreX items
  • Support for stack sizes beyond vanilla stack limits (up to 99)
  • To increase the stack size of a custom item, add 'stack-size: 99' to that item in customitems.yml.

Improved:

  • Much more reliable /ic create behavior for advanced custom items
  • Better support for custom weapons and attribute-based items
  • Stronger foundation for shops, upgrades and secure custom item progression

Fixed:

  • Custom items created from held items no longer lose important item data
  • Attribute modifiers are now saved correctly
  • Saved custom items now behave much closer to the original item
