It would significantly speed up diagnosing this type of failure if we include two additional pieces of information in the trace log:

    The step number where it failed. Then we can focus immediately on that step and skip the time it takes to determine which is the faulting step.
    Which dynamic target it was looking for that it could not find. It is possible to bind a step to more than one dynamic target. Without knowing which one the test is blowing up on, you have to guess and investigate all of them.

This will save time for technical support and make customers happier at the same time.
