Amazing job, there's 3 more lines i need you to translate. If you have the time.
There was some internal text that i had to move to the translation files in preparation for opening translation submissions.

UI_LazoloUpgradeSlots = "Upgrade Slots",
UI_LazoloCapacity = "Capacity",
UI_LazoloWeightReduction = "Weight Reduction",

Here it is.

UI_LazoloUpgradeSlots = "可升級欄位",
UI_LazoloCapacity = "容量",
UI_LazoloWeightReduction = "負重減輕",

oops, I found some faulty translations:

UI_UpgradeCapacity = "此套件可提升的容量: ",
UI_UpgradeWeightReduction = "此套件可提升的負重減輕: ",

I've update the file on github too.

Awesome! thank you. I'll got it and its working. i'll push the update in a little bit.

i was going to add both your translation and a russian translation someone made when i realised i had completely forgetting the context menu translations.
this should be the last of it.

UI_LazoloAddUpgrade = "Add Upgrade",
UI_LazoloUpgradeBag = "Upgrade Bag",
UI_LazoloRemoveUpgrade = "Remove Upgrade",

UI_LazoloFixUpgrades = "Fix Upgrades",
UI_LazoloExpectedStats = "(Capacity: %s, Weight Reduction: %s)"
UI_LazoloFixManual = "Manual Fix",
UI_LazoloFixManualDesc = "Update this bag's stats manually."
UI_LazoloFixOnce = "Once",
UI_LazoloFixOnceDesc = "Set this item's stats to the expected stats from Dynamic Backpack Upgrades",
UI_LazoloFixAlways = "Always",
UI_LazoloFixAlwaysDesc = "Flag this item to automatically update to Dynamic Backpack Upgrade values if it changes. <br> (Automatic updates only apply to items in a player inventory)",
UI_LazoloFixNever = "Never",
UI_LazoloFixNeverDesc = "Permanently hide this menu without doing anything. <br>Remove all upgrades to re-enable it.",


UI_LazoloTooFullToRemove = "Bag is too full <br>Removal results in %s Capacity",
UI_LazoloRequiresNeedleThread = "Requires: Needle & Thread"
UI_LazoloRequiresScissors = "Requires: Scissors"
UI_LazoloRequiresSharpItem = "Requires: Scissors or Sharp Knife"

Hi there.
I've updated the files on Github.

And I found out that there needs to be a Recipes_XX.txt to translate the recipes. I've added it and tested it, it works fine.

amazing, thank you so much. I didnt even think about the crafting recipes when i was setting up translation stuff.
I just pushed the update, let me know if there's any problems.
