Apologies for not responding earlier. Didn't see your post yesterday and am just checking in here today.
It looks like a number of the previous issues have been fixed and a couple more have downloads en route.
For YARN/YARNish items with this error, I know a fix that will get the assets to work but really just consists of tricking CM 3.8; it removes all but two of the vertices, remedying Content Manager 3.8's being unhappy with all those stretch points.
Please note: the assets themselves are not changed; just the config.txt.
Attached are my modified config.txts for <kuid2:124017:26050:1> [#1], <kuid2:506208:100079:1> [#2] and <kuid2:506208:100116:1> [#3]
Also here is my config.txt for the first, <kuid2:124017:26050:1> YARN Adaptor L1L2 (for example & discussion purposes):
description "A kazillion roads have already been created for Trainz but, nevertheless, none of them seem to meet everyone's needs. So I've created Yet Another Road Network -- a set of models mostly suited for modeling U.S. roads. These probably won't meet everyone's needs either, but hopefully some people will find them useful.
This adaptor allows a 2-lane road (kuid2:124017:26011:1) to split into two one-way merge-lanes (kuid2:124017:26025:1).
See the included naming-conventions.txt file for information about the attributes encoded in the asset's name.

Please note: All I have done to change/modify this config.txt is to remove a number of stretch points by reducing vertices per road to one (1). In some cases trying to modify YARN/YARNish assets, I also have had to reduce the number of roads as well but usually can get CM 3.8 to work with just one vertex per road.
As I said, it is not a great fix but it does work and consistently fools CM 3.8.
Please! If gigimmo or anyone else knows how to modify these properly I'd love to see that fix!
There has got to be a better way to modify the config.txt and keep all the stretch points but make them unique as CM 3.8 requires. Perhaps a stack or series of vertices (?); every time I've tried any other combination or sequence/syntax I get the same error/fault as Frimbo has experienced:
Error: Multiple track stretches between 'a.road_0_x' and 'a.road_1_x' in container 'attached-track'. Track stretches must be unique.
I just found a quick and easy way to fool CM 3.8. However, I can promise that I have never had an issue with any of the multiple stretch YARN/YARNish assets after using this fix.
Hope that helps Tom.
Please let us know how you are making out with getting Donner Pass running and if there's anything else you need help with.
Best Regards and Happy Trainzing!
