When I tried to copy Kim's first frame to frame 2, a new error appeared. Instead of placing it exactly where it should have been, this application combined the data with Shaniqua's data and destroyed the path effect. I tried different versions of Inkscape (there are enough to choose from), but it looks like a bug in the document, again. So I will have to waste precious time trying to find a solution. Probably I will have to export all perspective images from Shaniqua and have them re-created with LibreOffice Draw to import them back into Inkscape. Unfortunately, this is very, very inconvenient, but it cannot be avoided. Sorry for this new delay.
