Attributes not changing with Netherite
Summary
Describe the bug encountered in detail.
When upgrading diamond weapons, armor and tools with custom attributes such as Health and MovementSpeed with netherite ingots, the stats that should be increased do not change.
Steps to reproduce
Provide a full set of steps used to reproduce the bug, including links to SEPARATE Pastebin pastes for each relevant configuration file.
Step 1: Create an item with custom attributes (must be a diamond weapon, tool or armor)
Step 2: Get the item via /mm i get testbom
Step 3: Place a smithing table, get a netherite ingot and upgrade the custom item
Current behavior
Describe what happens currently, while the bug is affecting your server.
When upgrading diamond equipment that have custom attributes with netherite, attributes like AttackDamage and ArmorToughness don't increase.
Intended correct behavior
Describe what you think should happen instead of the bug.
Upgrading items with custom attributes should add the stats of their netherite counterpart (For example if I upgrade a diamond sword, the AttackDamage should be increased by +1)
Server log file
Provide a link to a Pastebin paste with a copy of your server's latest.log file from startup to "Done!" AND includes a player connecting.
Debug log snippet
Provide a link to a Pastebin paste with an excerpt of your latest.log file that includes debug output where you trigger the bugged behavior.
The issue is not server related, instead happens because of an issue of the game.
Proposed fixes
Describe what you think the issue or any potential fixes may be.
So, I was thinking of adding a "custom smithing stone" creator that allows to create a special item that when combined in a smithing table with a piece of equipment it will add the attributes specified in the smithing stone's config.
For example I create a smithing stone that adds +2 AttackDamage and +1 KnockbackResistance to MainHand attributes, when combining a diamond sword with this stone. the sword will have +9 AttackDamage and +1 KnockbackResistance when held in the main hand.
Here is the bug in game:
