I started a fresh playthrough and got "image 'dormtorio' not found" error when transitioning to Tiger's day 8. There was also another part that launched a script error but I forgot to catch it (sorry) and you can force past it with ignore.
I'm not sure if this is useful at all but there are a lot of peculiar words and phrases in the English version of the game. I assume this is more or less because of direct translation from Spanish?
