A Redditor posted a photo of the actual nylon bag people are receiving, and it looks like Bethesda has confirmed "due to unavailability of materials, we had to switch to a nylon carrying case." The listing at the official shop doesn't describe the bag, but the listing at Amazon still calls it a "West Tek Canvas Carrying Bag."
*Previously: "I’m suspicious that the real reason [the Spider-Man Collector's Edition statue] was obscured up until now is that, well… it’s a total mess."
Update:
We understand and respect that there is disappointment with the bag in the Power Armor Edition. We are sorry. Please contact Bethesda Support to provide proof of your CE purchase. They will assist in granting your account 500 Atoms.— Fallout (@Fallout) November 29, 2018

Ironically 500 Atoms won't even buy you the Fallout 76 postman skin that actually has a canvas bag (it costs 700) pic.twitter.com/UCN3kXYDmn— Chris Livingston (@screencuisine) November 29, 2018
