Oh wow really? That's so strange!! You know, I haven't had this problem in my game with the blacked out images in a very long time. And it was a few years ago I believe, and it only corrupted one of my saves. (In that same save, my custom painted pets turned black too.) The fact that it's now happening after trying a new save from any of my current saves is what's making me think this is a larger more technical issue with the recent patch. Maybe they'll tweak something and put out a new update with all bug fixes from today.... At least that's what I'm desperately hoping for!!
I just tested it with DX11 and the memory boost (early access). It doesn't even work. Why is the bug so much worse for me than in the previous patch? The “Save as...” function and then saving again worked well with the pervious patch.
