2nd player personal loot safe

Hello, me and my girlfriend are playing on PS4 splitscreen and as 1st player when i use my personnal loot safe on Sanctuary 3 , it saves my loot , but not her’s . She wanted to put it in his safe in order to use it for reroll. We rebooted the game and all the stuff on her safe disapear. Are you looking to fix this problem faster? Thank you very much

Its because you as the main player quit the game first.
Have your gf the second player quit the game not to main menu first then you quit they should be fine see my post i tested this out today and found a keep safe for now.
