Sorry not to get back to you sooner.
I think you will find this is not actually a problem, just a misunderstanding by yourself (which is not surprising, as there is no help for the clans). I did investigate after your feedback a while ago, and everything seemed as it should - and I even worked out why you were getting confused. But I have long since forgotten, unfortunately.
Can you let me know again what the problem was, and I will look again, and reply here, just in case there are others who have the same problem.
EDIT : I just went through the feedback log. I had sent an email to you saying "I could see no problem, can you send more detail". So, can you explain in detail what you mean by "clans have not updated after they have won or lost." Then we should be able to get to the bottom of this.
