From the following thread :
https://forum-en.gw2archive.eu/forum/livingworld/jubilee/Token-Wallet-Thank-you-a-net/page/9Fractal Relics (the regular ones) have been removed from Mystic Forge recipes. Those recipes now use Piles of Crystalline Dust instead.
With regards to dungeon tokens and crafting: You can buy Offerings from the vendors that sell you the dungeon armors and then use them in the crafting recipes.
Hope that helps
However, seems like the Offering for crafting isn’t working right (yet)
I can confirm that a Piles of Crystalline Dust instead of a Fractal relic worked at the Mystic Forge.
