It is a big download, so if you have an unstable connection, the downloaded files might get corrupted. Try downloading with a download manager.
Thank you! I think it was a connection issue, after i got the download to work i haven't had any issues since and I just got to the guild and washed off the minotaur blood. So far so good. Keep up the good work hope this game evolves into something great since i loved the Anime and always liked Hestia's chest.
