NextColony: It is no longer possible to bring a new Yamato from level 0 to level 20
Since there are now less than 16 days left until the end of the season, it is no longer possible to bring a new Yamato from level 0 to level 20 in the remaining time.
Each upgrade level takes at least 19.2 hours. Therefore, 20 levels require at least 16 days (384h).
