My understanding of the drama is Hugs was shipping progressively less substantive content, and eventually stuff was denied just for having unacceptibly low wordcount and such. Few scenes, short scenes, Hugs' writing quality can only prop up content so much of it's nearly nonexistent to begin with. When stuff was denied, Hugs took it too hard and either left, or was kicked for toxicity.
Bubs has been sleeping on Quin for literal years, but there is a certain cautious optimism that eventually Bubs will do his companion commitments and write more Quin.
Edit: Bubs has said that Quinn's first expansion has been submitted. For the uninitiated, this includes Quinn's second companion set, a heavy armored soldier type armor.
