Fix for #210

     function pickSubPool(pool, numElements) {
         // Assumes each element of pool has function "alwaysInclude"
 
         // First extract those excluded from picking process
         var picked = [];
-        pool.forEach(function (e) {
+        pool.forEach(function (e, i) {
             if (e.alwaysInclude) {
-                picked.push(e);
+                picked.push(pool.splice(i, 1)[0]);
             }
         });
 
         return picked.concat(randomSubArray(pool, numElements - picked.length));
     }
