Rocket League Fennec Disappeared from My Inventory—Fix This Issue Now

I purchased a package in Rocket League that included the Fennec car, but it disappeared from my inventory. When I deleted and reinstalled the game, the car reappeared briefly but vanished again a day later. This is incredibly frustrating, as I paid for this package and now can’t access the item I rightfully own.

The Fennec was part of one of the packages shown in the attached image, but I can’t recall which one exactly. I need this issue resolved immediately. If anyone else has experienced this problem and found a solution, please share. Rocket League, take responsibility and fix this inventory bug now—I want my car back permanently!
