I'm on Windows, and no there are no error messages. Also, I should probably phrase my complaint better - it's a mix of screen freezes and something I don't know the word for. Here are some of the errors I've encountered:
1) When going through the Craft screen and running down the list of items, the screen suddenly froze. I can still hear input sounds when I hit keys but the screen doesn't change.
2) When loading any save file, auto save or not, that's a normal battle or a dungeon floor, it throws me to the background image of the town. If I right click, I can bring up the interface, but nothing is really interactable. For example, if I click Shop it just does nothing instead of bringing me to the Shop page.
3) And then of course, there's the standard random freeze in the middle of exploring the dungeon.
EDIT: Oh, and one more error, you can't move through the save files with the directional keys. It's like they're blocked or something.
