So, let's be honest. Today is January 05 (!)... When would GR like to bring the "update"? I'm about to finish my patron. It's not worth emailing GR anyway, he doesn't respond! Sad, isn't it? He should rather stop the game instead of alienating the members!
I beg to differ. As I stated previously, I understand the impatience, but still, I'd rather see slow progress than no progress - and if you compare GR to some of the big names in development, this is a hiccup and still not too bad.
Besides, GR doesn't respond to your mails precisely for the reason you don't respond to the people asking which AI tool you use: he doesn't feel like he wants to.
You're both within your rights to do so.
That said, nobody can blame you for cancelling your Patreon. That's entirely up to you, and while I understand GRs position, I understand yours as well.
