"Failed to load dependency assets required for compiling this asset"

I knew I shouldn't have updated.

So I updated TRS19 to build 106618 while trying to solve another problem, and, as expected, about 80% of my content is now broken and/or missing dependencies, including built-in and official DLC content.

The most common error is "Failed to load dependency assets required for compiling this asset", as well as "TEDGetSpecFromAsset> Unknown asset <kuid2:xxxx:xxxx:x>". This is mostly JointedRail content, and stuff that worked fine before the update.

I have done three database repairs and these errors will not clear up.

What does this error mean, and how can it be fixed? More importantly, why does every update break things?

UPDATE: So I did some poking around and found that the asset causing problems was a dependency of the JR Train Effects library, that, for some strange reason, was deleted during the update. I reinstalled the library, and I am now in the process of another Extended DBR. Hopefully this clears things up.
