In version 0.1.1
1. When you right click the class icons to see what is going on, the "X" button to close that info screen does not actually work.
2. After you obtain a class, your master's EXP remains green, even though it is too low to obtain any other class.
3. You can't complete the Workers' Guild "food supply" quest, nor can you forfeit it.
4. You can't complete the quest "Wild Wolves" because you can't actually set your party or move forward in it.
5. You can't complete the quest "The Red Cave" because although you can move in it, advancing on the final stage is endless boss battles.
I don't know if any or all were fixed in version 0.1.2, but I didn't get a CRASH from any in 0.1.1.
