The Alchemist has an option to convert Ingolith to Obducite. I did this and and it consumed all 20 of my Neathiron instead. UI need to be fixed and players should be reimbursed since Neathiron is quite important for Masterworking.

It did the same for me! Lost so many hours of gameplay in 1 click 
Give it back Blizzard!
Just did this and consumed 563 Neathiron even though it said it was using Ingolith. Lost every one I had saved up. I would like refund of those items please.
This just happened to me as well.
I lost my 373 Neathiron same way.. Blizzard please let us have it back
Literally did this yesterday. Insane blizzard doesnt have a way to submit tickets for stuff like this. Dumb levels of oversight.
