Hi All,
This used to happen every so often, but now it seems to happen more regularly, where thumbnails in the project media are referencing other media in the project - to the point where it even crosses media type (a video clip thumbnail is actually that of a PSD in the project, etc.). Likewise, there isn't a consistent circumstance that causes it, but it does carry over if you close the file and re-open.
The actually media itself is the right thing, but it is obviously an annoyance when you have to read every title, as opposed to being able to just spot a thumbnail.
And, unfortunately, yes - this probably wouldn't be so much of an issue if I were still in my 30s...
