Today we're putting out a hotfix on PC for an urgent issue where Crafted Apparel stat bonuses were not saving when the game closed. We will be getting this out on PS4 and Xbox ASAP and will let you know when that happens.
We've also gotten reports of some players having issues equipping their main weapons. For now, a quick workaround can be to either drop the weapon(s) or place the weapon(s) in Storage, then pick them up again. This will work until we get a permanent solution in place.
