Bridgerton bundle items not showing up in build/buy mode on PS5
When I first bought the bundle, the pack showed that it had downloaded into my game, but the extra items (like the piano and archways, and such) did not add into my game until I closed and restarted the game and they appeared, but upon opening the game again, now the bundle windows (specifically the ones with the fencing in the middle) entirely are not showing up in my game anymore.
Proserrpiina for missing content on PlayStation you could try restoring your licences but also check your installed content because the bonus items on my console are installed separately, so yours may have uninstalled which can happen. See the attached information from PlayStation support. If the content is still missing, since it is purchased from PlayStation there's an option at the bottom of the screen there to speak to them directly, good luck.
