I have a bizarre problem I can't solve with the GC preset. The Black ship on e13 can go on a12 and I don't know why. And while on a12 it can go on a11. These moves are not at all allowed. This doesn't happen with the White Ship. When the ship is every where but on the raw 13, that problem does not occur anymore.

The Ship is supposed to move as a vertical half-gryphon.

The code is:

def s fn (checkride #0 #1 0 1 and empty #0)
    where #0 1 1
    #1
    or fn (checkride #0 #1 0 1 and empty #0)
    where #0 -1 1
    #1
    or fn (checkride #0 #1 0 -1 and empty #0)
    where #0 1 -1
    #1
    or fn (checkride #0 #1 0 -1 and empty #0)
    where #0 -1 -1
    #1
    or checkleap #0 #1 1 1;

def sL mergeall
    leaps #0 1 1
    ray where #0 1 1 0 1
    ray where #0 1 -1 0 -1
    ray where #0 -1 1 0 1
    ray where #0 -1 -1 0 -1;

I don't understand what's going on. Thanks for any help
