Expected Behavior

As well as the missing media source files, I expected the mask file to be found in the missing file search.

Current Behavior

Only missing media source files are found and fixed

Steps to Reproduce

1. Create a scene collection with media sources in it, and have at least one source with a mask on it that links to a mask image file
2. Export the scene collection and then reimport it (make sure to move all the media files so that when you import it OBS cannot find the files)
3. Open the newly imported scene collection and use the dialog box to find the missing files.

Anything else we should know?

Reproduce the missing-file search from the issue using a scene collection with an Image Mask/Blend filter and a missing mask image. Start at the missing-file dialog and the Image Mask/Blend filter's file reference; done means the mask image appears alongside missing media source files and can be fixed through the same search.
