Disabling castle shields during the event is not fully working. Neither owner nor enemy primarchs is now able to attack or use abilities with the shield down. Attackers get an error message after selecting a dragon.
This means we can’t do on-castle glory swaps, guard swaps or sales, kill visiting enemies, or do friendly or hostile conquers. There’s no way to transfer a castle that’s been surrendered in the past week.
PG should not remove a major source of fun, progress, and social and economic activity from Atlas without really understanding what they’re doing and having a replacement in place.
