This has happened twice today where mid game I disconnect from a warzone match and lost 2 legendary warzone xp boosts because of it. I’m 100% sure it’s not my connection and it is the servers of the game. This has happened way too many times before. I need them refunded or something as I paid actual money for them. This is ridiculous.
Don’t worry, you won’t have lost any items. What happens here is that the opening animation for the packs gets skipped over but the items do still get deposited in your REQ inventory. You need to hard reset your console to see the updated inventory in-game, alternatively you check for new items here on Waypoint: https://www.halowaypoint.com/en-us/games/halo-5-guardians/xbox-one/requisitions/categories/customization?ownedOnly=False
