Sorry if this is a known issue; I did spend some time googling for it.
I decided to dink around with DF after a hiatus, so I downloaded the latest Starter Pack for Windows (10). I extracted it, ported some old clothing mods I liked to \raw\objects\, tweaked the inits, changed the graphics through the UI because I hate tilesets, and launched DF. As soon as I tried to create a world, it crashed, citing that it couldn't find \raw\objects\text\book_instruction.txt.
So I went looking for it, couldn't find it, scratched my head, and extracted the whole thing over the top without replacing existing files, figuring the first extraction must have failed. Launched DF, created a world, embarked, and looked around--but wait, my dwarves were in default clothes. Where was my mod? I went back into the raw folder and it was back to the default! How'd that happen? Plus the ASCII graphics weren't quite right.
Long story short, I puttered around for a while, then decided to delete the entire thing and start over. So I:
- Deleted everything
- Extracted the Starter Pack
- Changed the graphics
- Went to move my mods into \raw\objects
\df_42_04_win_s\raw\ was missing entirely.
Repeated the process. Changing the graphics from the LNP UI completely deleted the \raw\ folder.
I'm guessing that's not supposed to happen?
