Equipment not appearing in-game (but present on the website)

[MadeForFighting]

Short report: quite a few of my items are not possible to select in-game, no idea when this started. They are not new, in fact mostly very old. Is there any way to fix it?

typically this happens if you have too much total gear.  have you purchased stuff recently?  Sell off a 5 or so old items you dont use anymore and check
