I want to be honest with you:
I can only assure that the scenery, autogen and everything related to it work with the latest installer.
The autogen problems only occur in conjunction with a few other sceneries which replace / overwrite the Skiathos autogen or just have a higher
priority. This is all due to the way Prepar3D handles the autogen system, which is far from optimal unfortunately.
So after installing Skiathos, it should have the highest priority in your library, and you should not have any problems with the autogen
- if you do however , I'm happy to help 🙂
