Hey ngc,
I think Chris's message was intended as a heads up, considering he is part of the TS team

Shasta is primarily "my" baby, while Chris has the La Grande Sub and Sandpatch. The main takeaways here are 1. Just because Shasta is in the works does not at all mean there aren't other routes simultaneously in development, and 2. It does not make sense for a payware company who is developing a new Sandpatch to grant permission for their payware objects to be used in a project that would be in direct "competition" with their own product. Obviously if those shapes and/or textures are removed, then there is no issue from our perspective.
Also, I need to make this clear for future precedence: Although the TS Scenic Sub starter route is free to download, that does NOT grant freeware route makers the right to use any assets from it in their own freeware routes. The license that a user agrees to when installing the starter route specifically says that the end user has no rights to the intellectual property, and therefore no assets from the route can be redistributed in any shape or form
