Hey! We tested it out. So for the Character Skill being stuck, the freezing appears to be caused if you click through the text box too fast during this portion. If you allow the text to fully scroll, it will proceed and the game will work as normal.
This appears to be an issue with the text box behavior itself, which is why you may see repeating text here and during that Sage dialogue. At the moment there's no immediate fix for this until the engine is updated, but not skipping the game too fast should prevent most issues from cropping up.
