Siege stuck on workshop + map border + trees

Played a game where I squeezed my siege workshop in between the map border an trees on the enemy island.

After the first bombard came out, I couldn’t roll it away. It actually got blocked by trees and the workshop.
(I think this is a minor bug, because buildings you can always pass, even though they are tight build.)
