Update 21.12.20

 A few small changes and bug fixes for version 21.12.20:

- Fixed a bug with Kurohime's new scene
- Fixed a bug with Wendy's third squad ability. It was endlessly available and unlocked Kurohime's third ability.
- Added background music to the deep mine.
- The CC is now accessible from the worldmap.
- Fixed a bug that caused the arena to be re-build after you constructed the archery range or university.
- Added a note to the difficulty choice in vanguard battles to explain that the choice does not change the rewards.
- Added a more detailed explanation about how to recruit Kurohime to the vanguard forces to the walkthrough.

Since several people has asked about these things:
- In order to recruit Kurohime as a squad leader, you need to tell Theremis to prepare a war against Dorgania, and you need to advance the events of Grey to have the meeting with Lady Akira.
If all necessary conditions are met, and Kurohime is in your service, a spy mission will become available at Luolambo on the country overview map. This spy mission unlocks her as a squad leader.
- The second archery training event on the command center screen does not only require 2 elvish artifacts, you also need to recruit Wendy as squad leader, and Mirel and Elly need to be in your party.
