That would make it optional not avoidable. Optional is it happens but you don't have to see it avoidable is it doesn't happen.
I think in this forum the word used for "you can chose not to see it but it still happens" is "skippable".
As I understand the terms, "Optional" is a stronger subset of "Avoidable".
Basically, when it's Avoidable, the scene will happen unless the player prevents it ("Hey, you slut, what are you doing? Stop it!")
Instead, when it's Optional, the scene wouldn't happen unless the player pushes in that direction ("Hey, you know, it would be hot if you...")
A very blurred distinction.
I read on Discord that the errors with Monique's room and the University hallway have been fixed, but the fixed version can only be downloaded at the Patreon site for subscribers. Kind of makes me wonder whether some of these exception errors were done purposefully to raise revenue.
I didn't even know they were doing public releases of the current chapter.
I see it more like "not caring about the leeches" than "let's tease the leeches with a bugged version and then promise them a fix if they start paying". Doesn't sound like a way to gain the trust of the players (and in fact, they've lost another couple of dozens of Patrons in the last month).
