This isn't an in-game bug this seems to be a bug with itch.io
I installed the game through the launcher and the launcher missed most of the images and possibly some back-end files as well. The only fix I found is to download the game through a browser and copy all the files into the game folder.
I will update this with anything else I find cause no, I can't be bothered to read all 8 pages of this every other day to make sure no new bugs have been reported by other people
Update. The only game breaking bugs I've still got are:
- The Blacksmith Husband (File name has a space at the start in the game code)
- UPDATE: Missing Birth options can be reliably "fixed" by interacting with the "chairs" outside of hotsprings, interacting with these seems to force the game to detect your power level thereby fixing the bug. The indicator for if this has worked is the voicelines characters give when at any given power level
- The displayed image still tends to bug out sometimes when at max power level for some reason
- Sanura needs to unlock 200 max power, after this she can be "fixed" the same way as the other two (except for her max preg lvl, I don't know why but specifically that does not work)
- So cow dungeon has a slight issue with the ending not working beyond fighting the boss, all the collisions don't actually change and trying to leave the room just restarts the boss fight
