Well, lesson learned. There are some serious issues with how games are pre-bundled with season passes.
I just had to request a refund from Sony regarding Dying Light Ultimate Edition pre-order because the Ultimate Edition did not actually contain a working Season Pass.
In this particular case, I suspect when Sony corrected the Gamestop error they caused a second error by not adding the Season Pass (entitlement) to the Dying Light Ultimate Edition bundle they were selling.
I can see this through my purchase history and expanding the Dying Light Ultimate Edition Bundle and see nothing in there that would function as a season pass.
There is a link to a broken "Dying Light Season Pass" that's available to download - this was part of the original "Ultimate Edition" but it's 0kb (making it look like it was removed, but never replaced) . The end result is that PSN errors out (error CE-37700-7) when attempting to download it.
Glitched Ultimate Edition owners like me can actually see a separate "Dying Light Season Pass" that's available for sale, while DLC content that was supposed to come with the season pass is listed as on sale for $4.99.
There is a separate Season Pass and Dying Light game that actually works, but the Ultimate Edition Bundle that was supposed to come with a season pass does not actually work.
To Sony support's credit, the guy on the phone was helpful in getting the refund done. Phone Support seem to know about the error but it's nothing low tier support personnel can take care of. Playstation phone support is blaming it on the developers, but it seems more like an issue with the publisher (WBI) and store operator (Sony).
The easy fix could just add the working season pass as part of the Ultimate Edition bundle, but that would probably take months to correct assuming they have to go through all the proper channels and submitting trouble tickets to various departments.
The fact that it's actually easier and less of a hassle to buy these things separately meant it's just easier to get a refund and buy the bundled items separately instead of buying the bundle.
