A "bug" was reported in the software. Turns out it's not really a bug, but a feature request, in that it's a piece of information that has been requested to be added to the output files that has never been there in the first place.
I'm trying to add it.
The software is not designed to have this information be persistent. The design of the software is a whole 'nother story, but suffice it to say that the information is there, but where it exists is not in a place where I can save it without burning a huge buffer. The place where I can add it safely, it no longer exists, because it's been overwritten. It is time-critical, so I can't save it and write it later. I can't change the file format because that would break compatibility.
Pain. In. The. Ass.
