I very much respect you for posting sales numbers despite not looking too good.
Many GB runners will just ignore their own thread if the numbers aren't too hot.
I feel the concept was very interesting with the two themes, some interesting colors and pretty cool and unique metal artisan collabs.
But maybe the inspirations were a bit too niche for running 2 base kits, on top of a lot of people being a bit less inclined to join GMK sets atm due to the insane wait time and December not being the best month to run GB's.
You clearly put a lot of efforts into this, and I hope the numbers pick up or something can be done to save the set even if it means cutting the Latin base kit for example.
