When we built the arrow enumeration we assumed that the arrows would only point in the 6 cardinal directions. This doesn't work for anything that is not cubic because the symmetry group doesn't map the arrows to each other.
Given the fact that we have no intention of fixing this (it's less of a bug and more of a design flaw), especially given the apparent lack of interest. I'm going to close this.
