I have two options on the preferences page...skip seen text or for skip
all text. It's always been selected as the seen text for me, so if it's been messed up with, then I can't see it from the options screen as nothing has changed there. I started this particular game from scratch with version 0.8.24.8. The seen text option does not work unless I first save a game, then put on skip all text, and let it run for a while. Then I can load up the previously saved game and use ctrl for skipping through previously seen text when I want to.

.. up to the point I used "skip all text" for, obviously.
If I open up an earlier version of the game, like 0.8.24.3 and load a savegame played with that earlier version, the Skip seen text works normally.
So it looks like I have to "read" the story in 0.8.24.8 either by reading it for real or "reading" it with "skip all" before that "Skip seen text" will work as it used to in earlier versions.
EDIT: Not a big issue for me if this is all there is to this particular side-effect. Just letting you know, in any case.
