So why doesnt this add on work on PS5 when the rest of the game does? 

[ajb1978]

Most likely because it was designed with the PS4 in mind, which is not a PS5. Most features probably would still work, but even though Sony does a fairly good job at backwards-compatibility, at the end of the day it IS a different console than the one it was built for.

That's one of the biggest downsides to consoles, the goal posts keep getting moved the moment you get close. So developers have to keep releasing new versions of the same game, either to address backwards incompatibility, or to take advantage of new hardware features.
