Since installing the Hogger patch, multiple mounts and skins that I had unlocked and equipped have automatically unequipped after opening the loadout menu, and subsequently vanished from the menu all together, preventing me from using them again. When viewing them in the collection, they still register as being owned, but I cannot equip them, or even see them in some cases.
For example, the Crimson Grave Warden Malthael skin is shown as owned in the Collection, but is locked in the Loadout menu with no purchase option available. The Flames of Judgement Charger and Malthael’s Phantom mounts have disappeared from the Loadout menu entirely, though they still display as owned in the Collection. Restarting the game did not fix the issue.
