[Custom Objects Not Showing Up When Opening]

I have the same issue, cannot see any custom objects in the objects selection in my mac and when I try to load a custom park/workbench it says "cannot load, contain invalid objects" so I guess the problem is the same for both my issues and that is that I cannot make the game accept new objects. Would love to see if there is a solution for this. 

[Brick path showing up as dirt path]

I have installed the latest version (yesterday) on my mac but when I want to build the colored brick paths it automatically builds the dirt/asphalt path in the corresponding color instead. This is in all scenarios I have tried, RTC1, RTC2 and expansions. I suspect the files for paths are messed up, but how do I fix it? I do not know how it is supposed to look like and where they are located.

Thanks!

 

EDIT: I looked in the objects selector and the object for the path is there, but the image is the wrong path. It also says: "Rollercoaster Tycoon 1 not linked - fallback images will be used"
