I'm away and unable to work on this mod before the end of the week at earliest. It's however likely that it'll take some time, there has been a lot of changes to the game and I suspect this mod/scenario is quite sensitive to changes.

Completely understandable.

Take your time

Github user asdfuser fixed this mod/scenario for Factorio 0.17, and as his changes were excellent I merged them into my repo and released a new version.
I've yet not been able to fully test the scenario, so it's possible there still are some bugs that needs to be fixed.

Wrong Category must be in [Scenarios]

You're right. Fixed. :-)
