Moving to Indesign forum.
I probably can't answer this, but is the alias in addition to the saved file, or in place of it?
It is in place of the saved file.

I believe there are other threads on this topic, but I don't recall a solution.
Launch terminal and use this command /usr/bin/SetFile -a a followed by the path name to the damaged file.
/usr/bin/SetFile -a a /Volumes/YourServer/ShareName/FileName.alias
/usr/bin/SetFile -a /Users/UserName/Documents/WIP/FileName.alias
The easiest way to get the correct path name is to launch Terminal and drag the damaged file to the command line, Terminal will create the correct path, now all you need do is paste the command in to the Terminal command line before the path and hit return.
I don't expect you will have this issue with InDesign files stored on your local HD, it most commonly occurs with files stored in a share on a Windows server.
