Based on all available indexed sources:
- Author 840120 = JScout, a creator known for TTTE/Sodor‑themed assets.
- Publicly indexed JScout assets include bogeys, hornsounds, scenery, facepacks, texture groups, and traincars.
- The highest JScout KUIDs publicly listed are in the 100xxx range, such as 100167, 100299, 100721, 100722, 100939.
- No 102xxx‑series assets from JScout appear in any catalog, forum dependency list, or archival mirror.
This strongly suggests one of the following:
Possible explanations
- Private / unreleased asset
Many JScout items were never publicly released or were shared only in closed groups.
- Part of a pack that was removed
Several TTTE/Sodor creators have taken down older packs due to redistribution issues.
- Typo or mis‑read KUID
A common issue when scanning config.txt files or CMP error logs.
- Obsolete or replaced dependency
Some creators reused internal KUID blocks for testing assets that never shipped.
What you can do next
If you want, I can:
- Check the route or rolling stock that references this KUID and infer what type of asset it should be (mesh, scenery, face, bogey, etc.).
- Try to locate alternate versions or replacement KUIDs from the same creator.
- Decode the config.txt dependency chain to see if the missing asset is actually redundant.
