Ernest, it is working fine I think. It is because of some complicated code I put to cull root moves that lead to inferior score when being in egbb. So for <= 5 man positions, the root is already inside egbb and any move that leads to a score less than or equal to the root score by a good margin is culled out. So if the root says draw 0 score , then all the moves that loose are removed. If the root score is a win, then all moves that draw or loose are removed.
So in those situations it can sometimes end up with only one move to play. Typically for test suites there is only one good move to play and this happens a lot. I just run it on MES testsuite, the first 20 or so positions were solved at ply 1 this way. My motive was to make moves very quickly and save time. I think your are good to go, just remember this when analyzing positions with <=5 men.
