I've installed all of the object files in the ORCT2 object folder and almost every scenery pack I select, I get the popup that says
"Following object not found: (and here is blank) Not all objects could be selected!“
As well as several of the paths I've downloaded not showing up at all.
I also downloaded a workbench.park file, and I can't open those at all despite them being in the proper folder, and I was able to open a different custom park without any trouble.
I don't understand what it is that I've done incorrectly.
