Guardhouses can’t be selected by using Find all archery ranges. I understand it is a mixed units building, but I expected a similar behavior as Dojos, that correctly can be selected with Find all barracks hotkey.
Other civs have special treatment of buildings so hotkeys can be used even if they don’t match semantically the type of units like Egiptian Siege works that can be selected by Find all stables
This along with the existent bug for Find all production buildings make cumbersome to play as japanese, one needs to manually keep adding any range building to a specific group as a workaround.
