Persistence in WCF Service using Entity Framework not saving!

I am testing my WCF service via WCFTestClient. My methods run for me and return the correct values. However, when I execute from the WCFTestClient my entities are not persisting. Here is the method I am testing:

public PlayerActionResult DoAction(PlayerActionType type, int uid, string pparam = null, int amount = 0, string svalue = null) 
        {
            Player player;
            PlayerActionResult result;
            PlayerAction action = (PlayerAction)Activator.CreateInstance(null, string.Concat("Conquest.Players.Actions.", type.ToString())).Unwrap();
            action.Logic = (ActionLogic)Activator.CreateInstance(null, string.Concat("Conquest.Players.Actions.", type.ToString(), "Logic")).Unwrap();
            action.Logic.Action = action;
            // Verify executor exists
            if (!PlayerExists(uid))
            {
                return new PlayerActionResult(false, ResultType.NotFound);
            }
            else { player = GetPlayer(uid); }

            if (pparam != null & !PlayerExists(pparam))
            {
                if (!PlayerExists(pparam))
                {
                    return new PlayerActionResult(false, ResultType.NotFound);
                }
                action.playerparam = GetPlayer(pparam);
            }

                result = player.DoAction(action);
                new PlayersRepositoryManager(entities).SavePlayer(player);


            return result;
        }

And here is the persistence logic in the PlayerRepositoryManager:

public class PlayersRepositoryManager : IPlayersRepository
    {
        #region Member Variables
        private GameDataEntities entity = null;
        #endregion

        #region Constructor
        public PlayersRepositoryManager(GameDataEntities entity)
        {
            this.entity = entity;

        }
       public Player SavePlayer(Player player)
        {
            var updated = entity.Players.Attach(player);
            entity.Entry(player).State = System.Data.EntityState.Modified;
            return updated;
        }
}

The "entities" parameter is a property of the WCF service "ConquestService" which contains the DoAction method:

GameDataEntities entities = new GameDataEntities();

The only value that is changing in the Player object is Movement, which when I test in WcfTestClient returns that is succeeded, here is the logic of that particular action.

public class PrayLogic : ActionLogic
{
    public PlayerActionResult Execute()
    {
        if (!CheckMP())
        {
            return new PlayerActionResult(false, ResultType.NoMovement);
        }

        Kingdom kingdom = Action.player.CurrentKingdom;

        if (Helper.GetRandom(100, 1) <= 25 + (kingdom.Honor + 1))
            kingdom.Honor += Helper.GetRandom(3, 1);
        return new PlayerActionResult(true, ResultType.Success);
    }
}

And the ActionLogic base class contains the CheckMP() method where the actual subtraction of the movement is done:

public abstract class ActionLogic
    {
        public PlayerAction Action { get; set; }

        internal bool CheckMP()
        {
            if (Action.player.Movement < Action.Movement) { return false; }
            Action.player.Movement -= Action.Movement;
            return true;
        }
    }

I have tried the approach above and I have tried calling SaveChanges() on the player object from the service method and from a method within the player object and none seem to work to persist the deduction of 2 movement from the player. ARGH. Any help would be greatly appreciated I'm eager to learn what I'm doing wrong, thanks!
