Nearly two years later and this bug is still not fixed properly. Sometimes when you place a bastion and save the map it will dislodge a wall (possible building as well) from the map space and move it back to the placement menu. The space where the wall/building was can’t be used until you pick up a few items near the space, exit map and go back in. Even then, the issue will reoccur as soon as you view the map again.
It has gone beyond embarrassing to a word I doubt exists. I’m sure this will fall on deaf ears but please take a few hours away from creating new pay to win artifacts and troop cards and fix this bug. Thanks....
