When loading a file made with Krita 2.9.11 that uses transform masks, the effect of the masks is lost. Test file: http://timotheegiet.com/kritaB/08-comicsB.zip Open test file. Content of the clone layers should be moved in the third case, but they are not. You can even see how it should look with the thumbnail preview of the file in file explorer... Doing it again in Krita 4.1.1 (using transform tool to make a simple move) and saving, it loads fine after. So it looks like a change in file format not handled properly, or something like that.
Yes, I can confirm the issue.

Fix loading of pre-krita-4.0 transform masks We should be more tolerant for older configs that do not have all the options we support.
