Wow, I think this game ate my DLC.
No matter how many times I reboot my PS4, check my add-ons to make sure it's installed, delete the game off my PS4 and reinsert the disc, and check the damn storage box, Tsukiyomi won't show up in my game. When I initially bought it, I didn't get the usual message, but I thought that was because I was in the middle of Mementos. I get home and try to access the box, but Morgana just gives me the generic "oh that must be your stuff" line. Go check the Velvet Room and neither Tsukiyomi or Tsukiyomi Picaro are in the compendium.
I'm legit getting pissed off trying to find out why I can't access the DLC I bought. Is there a way to redownload DLC? I can't find a way at all.
