MAKS airshow – Patrouille de France

Does anybody know what happened at the end of the Patrouille dr France display at MAKS on the Saturday?
They disappeared, presumably to reform for the grand finale, but didn’t reappear. After a long delay two appeared taxying in, with a further six doing a run in and break a long way down the runway from the crowdline. I did not see the ninth. Rumour had it that there was a coming together and one had to make an emergency landing. Can anyone confirm this?
