There are actually two bugs.
1. The script frozen after I killed the final boss. The narrator said something and told me to return
my realm. Then everything stopped.
Then, I closed the game and reopen.
2. After I loaded the saved game (just right before I killed the boss), I ordered all minions to march to the boss. Then, game crashed within one minute.
