Well, I’m making a rom Hack with a friend (which is a real fan of FE, I’m more newbie) for a group of friends. In this group, the vast majority has never played to a FIre Emblem game, so the tutorial is required. But we are changing completely maps, characters and classes.
By this way, on the 01 Chapter for example, Seth is supposed to use his sword instead of his spear, but the character that replaced Seth is a metamorph. A man becoming a wolf (we named the class Okami which is wolf in japanese, right ?). So he will use a dragonstone-like item and no swords. So the tutorial will just crash
I hope, this was clear enough for you.
And I will search again for an example of misstranslation ^^
