Partly dumb luck on my part since I opened hashmap file first just to see if there are some mistakes in GC.add/removeRange, and it was a hit. I just assumed it was wrong everywhere else ;)

Glad it was that simple. Thanks for fixing it for good.

Also, it is no exaggeration to say that the appstream-generator project would not be written in D (there was a Rust prototype once...) and I would probably not be using D as much (or at all) without the helpful community around it.
