CommonData not valid (Refresh units..)..

[repka3]

Hi all,
very quick question, if i missing something:

  ZetaDia.Actors.Clear();
            ZetaDia.Actors.Update();
            Logger.Log("---New dump---");
            foreach (DiaObject diaObject in ZetaDia.Actors.RActorList)
            {

                if (diaObject == null) continue;
                if (!diaObject.IsValid) continue;
                if (!(diaObject is DiaUnit)) continue;
         
                 DiaUnit Unit;
                try
				{
				       Unit = diaObject as DiaUnit;
				}
				catch
				{
                    Logger.Log("Can't covert Obj to Unit {0}", diaObject.Name);

					continue;
				}

              

                ACD CommonData = Unit.CommonData;
                if (CommonData == null || !CommonData.IsValid || CommonData.ACDGuid == -1)
                {
                    Logger.Log("Common Data Null for {0} -- {1}", Unit.Name,Unit.ACDGuid);
                    continue;
             
                }

[DiaUnit] Name:WD_ZombieDogRune_healthLink-5136 ActorSNO:110959

I get all data ok, summoning ZombieDog, if i recast Zombiedog then dump again, i get:

Common Data Null for WD_ZombieDogRune_healthLink-5344 -- -1992818254

If i stay with char in the same place, no matter how much spam "dump", still common data null. Sometimes teleport to somewhere, or waiting "sometime", i get back data ok. Is there a way, that i missing, to properly refresh unit (actors) ?
