This seems to have happened to a number of folks; all I can suggest at this point is filing a bug report through a support ticket - hopefully the support staff will be able to help out as well as let the development team know about the issue.
I just got my items at level 5 after finally figuring out how to get them and even the “legendary” stuff was well below the current greens I had equipped…at level 5. Massive disappointment and a waste of $100 so far. None of the “special loot” is special at all…it just made for some decent spending money so far.
Like many others I’ve had a glitch where I’ve opened the mail whilst in a vehicle and have o damage weapons…does anyone know if this had a fix on place/scheduled…it’s a lot of money to spend and not getting everything that was included
