It seems Bullion unintentionally stopped dropping this week! Blizzard have a fix on the way, however, plyers will have to wait until next week's reset to get the missing Bullion from this week.
Bullion (Source)
We identified an issue that caused Antique Bronze Bullion to become discontinued early unintentionally. Bullions will begin dropping again with the next weekly reset, allowing players to get the one they would have missed (the 13th) as catch-up, alongside the regular 14th Bullion. After this reset, Bullion will continue to drop each week until the War Within launches.
Thanks for the reports!

Discover how to unlock the Delver's Dirigible and explore the various customizations awaiting you in the War Within!
How to Unlock the Delver's Dirigible?

The unlock process is very straightforward. Once you hit max level and clear one Bountiful Delve in the game, you will complete the Bountiful Delves quest at Delver's Headquarters.

The subsequent quest from Brann will give you Delver's Dirigible, the base mount without any customization options.

Here is what the mount looks like in the journal.

Delver's Dirigible Customization Options
Just like Dragonriding mounts, you can customize Delver's Dirigible to your liking at the rostrum in Dornogal. Customization options include color, nose, wings, thrusters, top, and decal. 
You can buy customization schematics from the Murloc quartermaster at the Delver's Headquarters for Undercoins, a currency obtained at the end of delves.
You can also unlock them by completing the Season Journey for the Delves. In the screenshot, you can see a progress bar that fills up with each delve you complete, offering various rewards, much like Trader's Tender at the Trading Post.

Blizzard showcased some of the customization options at BlizzCon, but not all of them will be available in Season 1. They are likely saving some for later seasons.

We've also datamined a Void version of the mount which acts as a Full Transformation - Delver's Dirigible Schematic: Void and you can get it by completing the secret 13th delve alone as indicated by the Hunting the Hunter (Solo) achievement.

Various content creators have uploaded videos covering the customization in more details.
