I also had some issues with (what) giving me wrong results when dealing with both Counters and DoubleCounters. It was the same game logic where you place Counters, and when you remove them the Counters adjacent to it are replaced with DoubleCounters. The replacing was done with an (apply (remove (to))) inside (add). I suspect that this is the same or a related issue.
