Unless things have changed over the past ten years and some, publishers who port games do not get more $$$ to patch games. They get a lump amount included in the initial contract for X-amount of future updates. Games that
consistently require patches, or consistently receive "refresh" updates, end up sucking resources from the porting publisher. It gets to a point where assigning programmers becomes problematic because the porting publisher's company continues to secure other contracts. So, what frustrates regarding Aspyr and Civ6 would frustrate with any other company that had the Civ series porting contracts. FWIW.
EDIT:
I'm ready for the Spring Update as well.
