I completed the blast from the past event, but whenever I delete any cache files, all of the rewards disappear from my game. At first, restoring the old cache files restored the rewards, but now even that's not working. I haven't touched my "accountDataDB.package" file which I was told is where all the rewards are stored.
I added a screenshot to show that they don't come up when i filter all my in game objects by event rewards.
EDIT: I just checked again with no mods and cc, and the rewards are there. But then I tried removing only my mods and then only my cc, and they disappear with both. it seems like something about having a modded game is conflicting with the rewards, even though I haven't changed anything about my mods folder and it was working fine when I was playing earlier today
SECOND EDIT: I tired to create a new sims 4 folder and the rewards came back, but when I tried to add back my tray and saves, they disappeared. So I removed my saves and tray and they are still gone.
