Basically, I bought Fortnite Crew, it expired, I decided to master some sprites without the pass, bought it again and those specific sprites are forever locked. It’s quite obvious that the game sends a “unlocked signal” if you already have the backbling, but nothing happens if the pass isn’t active. After the pass IS active, the game won’t re-send the “unlocked signal”. The pod isn’t directly matched to your sprite status, it depends on this signal that was already used before.
