New Sims Delivery items missing

Hi all. I had the new items from the recent 25th Anniversary sims delivery (marble counters, new floors, new clothing items, etc) but now they're gone! How do I get them back? I've uninstalled, reinstalled, disabled and re-enabled mods. Refreshed Sims Delivery and it says I'm up to date. Started from scratch basically and I cannot get them back... HELP!
