If one of our downstream jobs is running behind (do to a lack of available resources on the particular node that it requires) the jobs are all collapsed together (like if we had a Quiet Period).

I wouldn't mind this so much but it uses the artifacts from the first job that kicks it off and not the last one. this means that we end up with a large number of untested changes.

As you can see the latest build was 2055 but it is using the artifacts from 2043.

We don't see this behavior when we are not using the Join Plugin.
