Silverstone Not visible

I can not find Silverstone in my tracks, if I browse through the tracks Silverstone is not present?
I thought that it was part of the original content?

 

do you have the GEC mod installed? This was causing problems, but there should be an updated version that fixes a couple of issues.

 

Are you subscribed to the circuit in the workshop?

 

Hi, thanks for the reply, what is the GEC mod?

 

I thought it was part of the original game?

 

Global Endurance Mod. It's in the workshop.

 

You have already said this before, but if you want to solve your problem you should check if you're subscribed.

 

Thanks for the reply, I was not subscribed, I thought that the Silverstone in the workshop was a mod, I was unaware that original content had to be subscribed to
