Hello support team. I don't find it right that gray castles are open to attack by everyone when they are conquered. When the players who have just started the game by chance capture a new big castle, the big players attack and take the castle from the small player. (especially the tyra players, Seguloic and Raswir). For captured gray castles, attack must be free only between players of the same level. I leave the matter to your discretion.
best regards
