How often does the bug occur? Every time (100%)
What is your current game version number? 1.68.156.1020
What expansions, game packs, and stuff packs do you have installed? Get Together, Vampires, Holiday Celebration
Steps: How can we find the bug ourselves? Custom Content does not appear in the buy menu. When searching by name i can find the description and hotlink to the folder that it should appear in. The names appear in the mod list when enabling mods as well. **Mods still seem to function fine, and have been updated Custom skins and clothing still function. I have removed CC, added it back and removed again. Adding back only CC that HAS been updated, but even THAT CC does NOT APPEAR in the game.
What happens when the bug occurs? CC just missing
What do you expect to see? my CC. about 500 buy/build items that all appeared in the game until recently. Now I haven't been playing the game TOO often, so this could have happened after July.
Have you installed any customization with the game, e.g. Custom Content or Mods? Not now. I've removed them.
Did this issue appear after a specific patch or change you made to your system? Yes
Please describe the patch or change you made. I believe the issue started with the lead up to Snowy Escape. But it could have started with the Journey to Batuu update?
