I'm using a data pack to allow turtle to wield a number of tools from mods, like gem tools from Bluepower, but the Experience Tools from Create Stuff Additions (https://www.curseforge.com/minecraft/mc-mods/create-stuff-additions) don't drop experience points when they dig blocks like they do when I use them as a player!
Here's the code that lets the turtles equip them:
{
"type": "computercraft:tool",
"item": "create_stuff_additions:experience_pickaxe"
}
