FOSS gamedev and creative worlds

Hi everyone, im making ores drop xp, to do that, i added the xp=1 group to the node and i added that to my api.lua, with default nodes it works perfect, but for moreores and technic, all i get is making those nodes "unknown", it's strange because with coal, iron, diamond, etc, it works, any idea how can i add the property without touching these mods, only mine?

minetest.register_node(":moreores:mineral_mithril", {
groups = {cracky=3, xp=1},
})

You overwrite the whole node, rather than just the group.

Use minetest.override_item()

It works!!! Thx rubernwardy, i'll vote you for president!
