Game crashes after unlocking new load screen

 Pretty much what it says on the tin. The past 3 times I have levelled up the season 2 Battle Pass to a tier that unlocked a new wallpaper the game has crashed the moment I go to look at it in the Game Customization menu. Just levelled to 44 and it's happened again with the Wraith wallpaper. Game is fine after rebooting and wallpaper is usable but it probably shouldn't be doing this.

On what I'd imagine is an unrelated note once I unlocked the Me, Myself and I wallpaper and restored the game after the crash the first time I checked Game Customization I mysteriously had access to Occtane's wallpaper, which subseuently vanished from the list after leaving the screen. Which is a shame since it was a cool wallpaper xD
