while it is certainly understandable why you think this way, and believe me I have seen these results as well. Please keep in mind that a majority of these Authors do not do this as their source of income. Their main employment to pay the bills take priority and if they have to abandoned a project because of work or family demands then so be it. they don't owe us an explanation, this is a hobby for most.
What certainly does not help is non supporters complaining and demanding, that is a #1 motivational killer. Ask your self have there been times you wanted to quit something, for example, your job, because your employer got into your shit like a drill sergeant instead of talking to you like a valued person?
And I did see that the mention of no patreon comment section not being regularly updated. What is being overlooked is the history of this author and their communication, it has been fairly regular. And their subscription tier as really small, unlike some of these other authors on here that have production level quality material, that milk and squeeze their subscribers for every last cent for YEARS with no content.
The author, while in the making of chapter 5 had a major setback when they lost all their renders for chapter 5 due to computer malfunction, and they did learn a valuable lesson on using external back up. Chapter 5 was planned to be a HUGE update. I feel their pain, all that work lost, having to redue all that work, hey, who would not lose a bit of motivation over a setback like that?
Then the author while in the midst of this had to relocate their residence, moving to a new location is time consuming and draining and as a result of this and community pressure for a release, chapter 5 was released outside the authors scope of vision.
I applaud this author for hanging in there during this trying time. I expect as the dust settles it will get better for this story.
