I think I was hit by something like this, too. I played the current Windows version, 2.2.1, and created a second base. It might have to do with me transferring something over to there, I don't know, but when I checked again I had about 60 items of lots of things, stuff that's quite expensive like aircraft armor and weaponry, things like UFOs, and even stuff that I never saw in the game before, like Miniguns. I'll create a post and add it to the other things that I found while playing.
