I verified and I don't get this problem (and you are the first to report me this).
Do you have errors in log?

Try code like
while (Conditions.InGameAndConnectedAndAliveAndProductStartedNotInPause && !Conditions.IsAttackedAndCannotIgnore)
{
var o = wManager.Wow.ObjectManager.ObjectManager.GetNearestWoWGameObject(wManager.Wow.ObjectManager.ObjectManager.GetWoWGameObjectByEntry(218889));
if (!o.IsValid)
break;
wManager.Wow.Helpers.Interact.InteractGameObject(o.GetBaseAddress);
Thread.Sleep(100);
}
(use quest profile and overidepulse... quest type)
