Factured fossil ruined my map, what am i doing wrong?

Hello,

I had a map with Nemesis and Beyond on it and I used a fractured fossil to duplicate it. It removed the nemesis mod.

Can someone explain to me why this happened? I've never used these so I don't understand how it works. But I thought it just added the split tag and created a duplicate.

fossils always reroll explicit mods

the only things you can keep with fossils are enchants/implicits.

for maps, this includes applied delerium orbs and the rare harvest 'enchant a map' mods

A resonator with the Fractured Fossil will reroll the mods on the original item,[1] and create a mirrored copy of the original. The fossil should not be used in place of a Mirror of Kalandra to duplicate mirror-tier items, as the original will be randomized.

Can't use them on enchanted items anymore, or influenced/fractured/synth for that matter. They got nerfed pretty hard.

Then what can you do with Fractured Fossils these days? Use them on random 6L items, like a chaos orb?
