New sbt "function" configuration not found in X / unresolved (transitive) dependencies

And a recent new "feature" in sbt, perhaps 0.13.7 or 0.13.8, is very annoying behavior when transitive dependencies are no longer encountered.

For example. I have a project A that depends on library B version 1.25.1, which depends on library C version 1.13.1. Naturally, only bibliographic dependency B is defined in A, because I don't want to define an entire tree from dozens of sub-libraries. Ok, this is building.

I am now updating the dependency in A to become library B version 1.25.2, which in turn depends on library C version 1.13.2. Now sbt is complaining about a rather useless configuration not found in library-C; 1.13.2: "master". Required from Library-B; 1.25.2 compile " and then throw out the" unresolved dependency . " Sbt didn't even bother to download the 1.13.2 C library from Maven Central or actually find it already published locally. The only way to" solve "this is to add the C library dependency version 1.13.2 to project A, which I don't want to do.

Here is an example printout:

I'm guessing this is an annoying bug in sbt, or is there any deeper arguments for dropping transitive dependencies that I don't understand?
