Failed to find shader map

So with the new update i was finally able to load my TC map, however i ran into this Low Level Fatal Error:

Failed to find shader map for default material WorldGridMaterial! Please make sure cooking was successful.

When i cooked the mod it showed no errors and uploaded to steam just fine.
Any one know what this is and how to fix it?

So i found out what the problem was, for anyone that may have the same issue.
I had not set up my landscape textures to the correct materials, and that was what was causing the crash.
