When I logged on today the first thing I did was claim my finished items from my Foundry and one of them was an Ivara, but she isn't showing up in my arsenal or inventory. Everything else I claimed showed up in my inventory no problem.
Figured maybe it was just a bug where crafted items were taking awhile to show up in my inventory as that's happened before. So I ran a few missions and about an hour later still nothing.
Update: I'm an idiot. I crafted a helmet, not the warframe.
