If you don’t think it’s technically possible, you could have just said that. I was imagining it would work as hitbox of two overlapping rectangles, not actually an octagon. The cropped bits would just be visual. But if that doesn’t work I’m open to other ideas. The fact is that what we have now clearly doesn’t work and literature anything would be better. I’ve added an alternative option of just merging two fields together and possibly even giving two build options in the grid.
