Unknown dependency

Hey everyone.

I tried downloading one of those Amtrak phase III MHC boxcars from the DLS, and I found an unknown dependency.

Unknown Location: <kuid:138423:112129>

I've tried looking it up on Trainz Kuid Index, but found nothing.
You should try again at trainz:kuid:index. There are 4 links for the missing kuid.
At trainz:kuid:index for kuid:xxx:yyy or kuid2:xxx:yyy:zzz
author id = xxx
asset id = yyy
version = empty or zzz
By leaving the version empty, you will get links for all versions known to the database.
