I started quest at lv 120 because I didn't get 4th job notice/quest when i hit 120.
I figured because I didn't do that required quest. I collected items it required then it sends me to the map The Desert of Dreams but nothing happens nothing and I'm stuck there.
I can't Job Advance due to it.

Quest says:

Secret Alchemy Request
Low Level Quest
Over Level 80

Secret Rendezvous
Han the Broker wants you to give the Matter Disassembler to the client at The Desert of Dreams in his place. This might be a good Chance to get some more information on the core.

Nothing happens when i go there.
