So the mode was P and converting to RGB fixed the thumbnail issue, but it didn't fix the rotate problem. It very noticeable, because I'm using expand=True with a white background test image, and the edges are very jagged. I'm saving as a PNG, and there's pretty much nothing going on other than a thumbnail and rotate.
Any other ideas?
