```yml
crafting:
shaped:
'1':
- m MATERIAL WEAPON_POWDER 1|m MATERIAL WEAPON_POWDER 1|m MATERIAL WEAPON_POWDER 1
- m MATERIAL WEAPON_POWDER 1|m SWORD PLATINUM_SWORD{level=2..5} 1|m MATERIAL WEAPON_POWDER 1

Suppose the latest item has less gem slots / different colored gem slots, or you set keep-gems to FALSE. In all these scenarios, gems are 'lost' so that this config option (**true** by default!) gives them back to the player.
Enable in your config:
```
# Options for the Item Revision System
item-revision:
# If an item is updated, and the new version does not
# keep its gems, this will give the gems back to the
# player so that they don't get lost forever.
drop-extra-gems: true
```
You can now go to your config and add, under item-revision:
```yml
item-revision:
phat-loots:
display-name: true
lore: true
enchantments: true
soulbound: true
upgrades: true
gemstones: true
modifications: true
external-sh: true
```
Which will update your PhatLoot items to the latest format in `/mmoitems browse` as they are generated for players. Since this will regenerate items, the *Unstackable* ItemStat now works with PhatLoots also
***If this is not added to the config, ** the default is that all options are false, and the items are completely regenerated and RNG-rerolled.
**Update MythicLib**
Pro tip: Its not implemented in-game but you can write it in the config files directly:
```
crafting:
smithing:
'1':
input1: SWORD.HEARTSWORD
input2: SWORD.ORACLE_SWORD
# Makes extra gems drop instead of getting lost
drop-gems: true
# If both inputs have upgrades, how to treat them?
# upgrades: ADDITIVE # Sum them
upgrades: MAXIMUM # Largest of them (Default)
# upgrades: EVEN # Average
# upgrades: MINIMUM # Minimum of them
# upgrades: NONE # Actually just dont keep upgrades
```
