So I have a document with some elements linked, .afdesign files.
When I link the file, everything works fine, they showup in the layers stack, they are visible on the canvas and I can manipulate without problems.
If i save the "main" doc with the links and open it again, most of the linked .afdesign documents become invisible, and I need to "Replace Document" to make them showup again during this session. If the main document is closed (after saving) and opened again, the links may be invisible again, and I need to repeat the process.
This behavior started after version 1.10. embeds have no problems, but with linked .afdesign files this problem happens often.
