P: Files created with Frames from shapes don't retain Frames
In latest version 21.01, running on Mac Pro Mojave - converting shapes to frames work while file is open, but when file is re-opened, frames made by converting shapes disappear, leaving only blank frames with no image. Layer palette shows frames with placed images, but they are gone from the image itself. Very annoying bug, as it means layout files with custom shape frames can't be revised - they're corrupted the next time you open them. Has happened consistently
