I don't usually play visual novels, except for ones like Slay the Princess or a few of the Chinese ones.
I am actually a programmer, and I've been looking for similar work in game development. Bug fixing is something I've had to do on my own and it something that I am stronger in. Usually to find bugs, you have to do things in ways they weren't meant to do. I imagine in a visual novel a bug would show up as the story itself not making sense with the choice. The best way to approach this would be to record the entire gameplay session and rewind back to the moments before the bug, then detail what I think caused it while also sending in the video. Also, if I can replicate it, then it means I know what is causing the bug, which is far more helpful.
