I've been swamped with people asking me to look into this game to fix issues every update. Developer really needs to rework a lot but that's not something I can change. So a good rule for everyone: Starting a new game won't fix some issues many times. You need to literally delete the Ren'Py persistent (a file) and not use old saves. In short, delete the saves folder under ./game
*and* the persistent file and (persistent) saves (Linux: $HOME/.renpy/LDD-...
, Windows: WTF uses Windows anymore since the abominations 8+, Mac: No clue, I don't use Mac). Again, starting a new game won't fix *persistent* (actual filename) issues tied to this game. Edit: Yes, this resets everything entirely. That's the point.
Edit: This won't fix obviously fix issues unrelated to persistent. A good example would be a non-default name (on a clean installation only, that's when this one can show up). It's as if the developer's never touched a programming language before.
