I have updated all of my 19-AD parks with .prk files based on the original OOTP19 .prk files. So, now you can import these parks.
For those new to these files, they are the parks that come with OOTP19 but with different signage. Some have graphics on the TV screens. In order for these to work you must also down load the advertising-19-AD file and extract it to the Models folder.
Here is the link to the files.
