When you click on the 'Hero' at a1, it can go to c4, and also the War Elephant on d2 can go to f1. This isn't right is it.
Refresh your browser cache(Shift + reload). There was a bug in the Betza parser of the diagram that caused this. The directional modifiers of a continuation leg are normally interpreted in the (8-fold) K system, so that even on 4-fold aoms like W or F you can use fs to get a 45-degree bent. But absence of any directional modifier in a continuation leg is defined as 'all directions except back to the square you came from', and the meaning of 'all' should only be 'all orthogonal' if the original atom was 4-fold. So that aF means two F steps in arbitrary direction, not an F step followed by a K step. The diagram was allowing the latter, though, and I had to fix that.
