I'd say Obito was the biggest problem before, but the new Ame orphans ages are even worse. Yahiko being 15 creates a ton of new problems:
 * Jiraiya supposedly trained Nagato before Minato, judging by his face markings.
 * There were at most five years between Jiraiya leaving Amegakure and Yahiko's death, meaning basically no time between the second and third wars.
 * Yahiko must have died two years before Obito joined Madara, which isn't possible.
 * Yahiko's corpse aged? Deva Path Pain clearly wasn't a fifteen-year-old.
