GOG staff could always subscribe forum threads and make their works easy.
Why should they? They are the ones DOING these updates so it should be easy for them to add update flags.
But you know, GOG staff rarely read forum threads, and often ignore bug reports here.
I disagree here as well. There are some bug reports here that they have been ignored but at least those important were mostly fixed by Judas when he read about it. The update flags are probably not very high on their priority list so maybe that's why they don't answer to your continuing complaint about them being missing. That still does not make it right but if you'd ask me I think they just prioritize because of limited manpower.
I think they will discard update flags sooner or later, like what they already did for the past few years.
For the past few years? Update flags did not work perfect or even good as long as I can remember. Imo this has neither get better or worse. It's inconsistent - the way it always has been.
