It should remember and skip sections already, as this has been a ren'py feature for a very long time. It might be an issue with your system or game files. I'd suggest double-checking things on your end, test other ren'py games, check that your save are working correctly, check your skip settings in Preferences.
No worries!
If you choose a different choice, you should always get a chunk of new text adapted to that choice.
There are probably a few lines of text that are duplicated in both routes, which might look like skip isn't working correctly, but for the most part the branching script should be unique to each route.
I'm not sure if you are referring to those small bits of duplicate text, or are encountering larger chunks of unskippable common text, which would be a bug. It might be useful if you can give me some examples of where this happens.
ok! First one that comes to mind is when (at the Sanctuary) you choose between those two choices when The Puffball (forgot his name ¡-¡) shows his amazing nails. So like, i've played this a few months ago (before 0.16), and I remember him giving Rheamus his little gift to the road. When playing again, after that scene, i remembered that he didnt gave him anything this time, so I tried to go back and choose the other line. After that little scene between them, the skip button didnt want to skip the common text (it being that "fight" with Chilas, which i read before going back), so I had to use the "skip unseen text" to get back to where I was.
Does this help? I kinda didnt finished it yet, so I cant actually say if it happens more times after this (atleast, in the new updates).
Yes, that helps, thank you!
Inside the script those parts should be common text, so it should allow you to skip it if you've been through it already.
Occasionally I go over older parts in the story and make small adjustments, rewording things, updating sprites, or changing transforms. I'm not sure if this is the case, but I'm guessing that might mess up what ren'py considers seen or unseen text in some situations.
I'll look into it.
