Artifact download task can not download shared artifacts from a specific branch

I have a chain of dependent plans where every next plan is triggered by a successful build of a previous one: A->B->C->D, and requires artifacts from previous builds: B from A, C from A,B, etc.

All this works fine for the default branch but fails for a feature branch. The triggering part works well: A of a new branch triggers B of the same branch, then C, etc. But the artifact download task pulls artifacts from the default branch.
