I've designed an app UI with Affinity Designer where I have multiple images laid out. The layout has a mix of portrait and landscape photos. I copied each of these types of "components" to create the flowing layout of images. I then switched out the photos within each of these "components" so that I had some variety in the UI. For example, there are 6 photos shown and 2 of them are portraits while 4 of them are landscape photos. So, all of them were unique when I saved the file. After reloading in Affinity Designer it shows all of the portraits the same and all of the landscapes as the same image! When this first occurred to me I thought I'd done something wrong but then I fixed all of the images and saved and it reverted back again. Even saving to a new file and loading that had the same weird result. I suspect it is somehow keeping a "pointer" to the image it had when I copy each of the "components" that include the image. The really strange thing is that the thumbnails look fine- so I know that the changes should be in the file, but when I open it in Designer it loses the changes and when I resave as a new file that file now has thumbnails that show the duplicated images. I'm going to try it in Designer v1 to see if this is just a new issue in v2.x.
