I was trying pieces that would need to end their move just before or after a friendly piece, such as (dauf)F, for example. It's able to pass through friendly pieces, but the last passed through piece is never unloaded. Something like yaodfaubQ also fails to unload. Maybe these are too obscure to bother with.
