Hello,
So you are suppose to have 3 crates, like had the vault bar grant you a crate 3 x but never seen them in your inventory? - system is bugged until a fix is released and or if you scroll down in your inventory you could see them ?
You have completed the objectives and you are not granted your jammies or hat, have you tired to customize your character in the menu? - could be bugged as well, and possible fixes.
You would need to use those 5 tickets to craft it into an item from your inventory, select the tickets select use to craft. - Player beware, crafting is also bugged an will cause you to lose that item but i yet to hear from ticket crafting to be bugged but since you have to craft there is a chance.
Hope this helps.
