The previous spot before that was inaccessible was two spaces in front of banner and 3 spaces to the right towards shrine.
Another one of those pox things that is hidden in a small area nobody sees. I did that but typically they only see bugs when they are posted here hence we go months with the same bugs, like this one. I reported this same bug months ago on the same map with a different space.
Like when you have a unit with Hidden: Veg and you're like 'Is that dirty mound of grass dirt or veg???' and it isn't and your unit dies.
