Zoro will tell you about the message then tell you about the different transformations, and tell you to become an orc to train with Blood to progress the story, as for the error code, can't you ignore it, or is that not possible, also for the transformations, it's a whole different dialogue option to get the potions to transform
that did happen about orc and training with blood orc dude and yes I can ignore it but apparently there’s more to the quest (I think) where he tells you to find a partner in crime but the quest is already completed UNLESS that’s a different quest, rn idk if it’s important but I did a quest we’re u gotta win against the street rat for the rematch using the fight app
