So I've been building up my vault and sending out dwellers to the wasteland for a a few weeks now (haven't missed a day!), but I noticed no new outfits seem to be coming in (they always collect the same old outfits I have already). Today I looked at the collectables page and apparently I've unlocked a whole bunch of new outfits recently, ranging from uncommon outfits to rare goodies that haven't even been showing up in my inventory. Whether these are being collected but appearing as duplicates of previously collected outfits, or just aren't showing up at all, I don't know. But is there some way to fix this without starting a new vault? I'd hate to have to have all my progress lost...I've literally been playing since day 1.
Also this doesn't appear to be happening with weapons, but I've noticed new guns seem to take a lot longer to find than outfits (this is normal?).
P.S I'm running this on an Ipad 2, IOS 8.4.
