Trainz

Is anybody else having faulty dependencies for the 100 ton coal hoppers?

The specific issue resides with the coal load dependencies, all of which show as Faulty. Closer inspection reveals the following errors:

The *.texture.txt file is missing for texture resource 'coal.texture'.
The *texture.txt file is missing for texture resource 'icon_texture.texture'.

Any help would be appreciated; I want to run unit ore trains with these specific cars.
