NOTE: It looks like the number textures is referencing the wrong folder. I will correct and have just reissue to the file library. When the new file is in the library, just re download and install.

In the meantime, for those who want fix it now, just edit the Dash9_Digits_NS.bin in the engine/texture folder for each repaint and change the file reference for each number texture to reference the texture in the weathered folder.
For Example:
Change:
<TextureID d:type="cDeltaString">RSC\Dash9Pack01\RailVehicles\Diesel\Dash9\
NS_Lifesaver\Engine\Textures\[00]primarynumber_0</TextureID>
To:
<TextureID d:type="cDeltaString">RSC\Dash9Pack01\RailVehicles\Diesel\Dash9\
NS_Lifesaver_W1\Engine\Textures\[00]primarynumber_0</TextureID>
For all the number textures in each weathered version (W1,W2,W3).
[UPDATE:] The file has been updated in the library. Please re-download to correct the missing texture issue.If any other problems, please let me know.
Thanks
