Is Tinderbox 8.06 compatible with the Apple 10.15 release?<strike> [yes, to best of our knowledge]</strike>

I am experiencing the exact same issue.

I get this error every time I click on any link: App could not be opened.
Then the link disappears. Also, all the links in the rest of the file are quickly disappearing as well. As you can imagine, this is a rather destructive problem.

I imagine it must have something to do with the relocation of apps to the System folder.
