Missing Scenery

I have missing Scenery on the ECML-S with Moorgate and Royston extensions

It ran ok a few years back when I last used it but now its in an unfinished condition
Looking with RW Tools it tells me I'm missing a number of DTG/RSC Assets even though all the relative routes are installed.
Two pictures at Hertford North



Not sure what to check?

 

Hertford loop scenery is in the rework of ECML-S from ATS. Those missing assets may just be reskinned versions of the defaults.

 

I will have to look to see if I have a backup
Not sure why it should revert to default?

 

A lot of 3rd party routes install additional assets to DTG and RSC folders - they might have been lost on the way.

 

Is that the workshop extension?

 

I think I found the route, it's from "wagn". But the download link is dead.
