I think this is getting to detailed - and I don't think many people are going to use our icons to look for tacticle maps.

It's a small fix, but I think it's just closer to the map than board, so I would fix it.

Thanks for fixing this detail! Tested and it works.

Even if this is small issue indeed, I think this might be important difference in how we see the map: I am not looking for things on a static map, rather I look what is there.
