Redwood Negotiations does not allow a surrogate response to be created when a draft exhists.

When attempting to submit a surrogate response to a negotiation that closed Redwood would not allow me to create a surrogate response because the supplier had an open draft started.

When doing this in Classic the error comes up but allows for the draft to be deleted to allow the surrogate response to be created.

Why would Redwood remove this critical functionality? Is this on the roadmap for a release/patch??
