Where did it go?

[Drgnwrtr]

Hopefully I can get some answers here, I've looked and googled everywhere. My question is about collectable synthesis, my goldsmith turned 50 and it didn't show up. I'm now level 60 goldsmith and level 50 alchemist, I still can't do collectables. Can someone please point me in the right direction?

I've already unlocked the collectables chain and can do DOL collectables, I just can figure out DOH collectables and where the button is, it's very frustrating.

Thanks!
