[2020] Many roads have disappeared and some tracks/roads have appeared.

More information will help us help you. Are we talking about roads/tracks from the workshop? Or the default ones?

Have you added/removed any mods lately? Have any of the workshop assets you use updated recently?

Below is some logfile, not sure how much.
Just realized too that road tabs are missing when I press road tab.
Have uploaded screenshot. How do I show it to you?

It's best not to copy a log (or part of it) into a post here. It's just too long. You can upload the file somewhere else and link to it. That's the easiest way to share it here on Steam. These sites let you upload a file without having to register.

https://uploadfiles.io/ - free, no sign-up, can handle large log files
https://paste.ee/ - fast, no sign-up required (some log files will be too large for it though)
https://zerobin.net/ - bit clunky, but can handle huge files, no sign-up required

Missing road tabs sounds like you used to have Network Extensions 2 and the mod is either disabled or unsubscribed.

If you've set the screenshot to public, just go to your profile and find Content. Then go to screenshots, find the screenshot and click it, then click the cogwheel on the right to share it and get a link, which you can then post here.

Have a look at Network Extensions 2 to see if some of the roads you're missing are from that mod. Afaik it's the only mod that adds more road tabs, so if you're missing tabs, it sounds like you used to have this mod.
