Did you use `Pkg.add` to add `A` as a dependency to `B`? That would fully explain your issue since `add` records the current commit that repository and keeps on using that unless you call `Pkg.update` to change to newest version. If you want to use `Pkg` to just load whatever happens to be at some location on your machine you need to use `Pkg.develop` instead of `Pkg.add`.

The documentation might help you: [`Pkg.add`](https://pkgdocs.julialang.org/v1/repl/) and [`Pkg.develop`](https://pkgdocs.julialang.org/v1/repl/#repl-develop)
