Sadly due to how Ren'py works, that takes a really, really long time: I have to edit the line, regenerate its code in a spreadsheet, find the voice file and rename it with this code so the program knows where it has to be attached and recheck it plays properly. Same process to change it in translations as well.
There's only about 4-5 little mistakes like those in the whole game so far, so it'll have to wait for now. I'd rather spend my time more productively :<
