Hi,
I emailed the Devs about a week ago with this bug, but i haven't seen a response so I am assuming it must have gone to the junk mail folder.
I have found a way to be able to see what hire options an enemy queen has, even when you can't see the enemy queen.
To exploit this bug, there is one pre-condition that must be met, but I'm almost certain this condition is met multiple times each game. (I'm deliberately being cryptic so that this bug isn't exploited).
I have two videos uploaded to my google drive that I can share to a Dev, which clearly shows the bug. (both videos were taken from different games). If a Dev can contact me I will share the links.
This isn't game-breaking, but it does give an unfair advantage if you can see what the enemy queen can hire, even when you can't see the enemy queen.
