In Scratch 11, a symbolic link was included in the .xo and unzipping
re-created that link. Someone else helped me create that mechanism
(sorry I can't quite remember who). But you are right, it no longer
works in v12, either because I changed something about my process for
creating the .xo file or perhaps because of a change in the XO
software (less likely).
I will look into this.
