Yeah I knew that part. It’s the “almost-all” part that I have tried. That’s how I figured there’s an issue. I don’t think the Rex Corona is supposed to show, but that I have tested other's that were supposed too.
I did a couple of times yesterday. However, this morning I noticed they showed up in my inventory. So, I do have them now, not sure how I got them in my inventory though?
I am having this same issue. The problem also seems to happen with items that you may change out from your loadouts. It won't let you sell those either.
