■Reportedly there's a problem with people not getting the cutscene from Monberaux and all he mentions is something about Wolfgang, the solution is to spam him (keep clicking on him) and you'll get it.
■Reportedly another problem when quest doesn't activate when speaking with luto. Going to rendez-vous point again, then zoned in pearl equipped may have helped


I did some more digging and for level break from 55-60 there were the above edits for getting the proper cs's, plus wiki also mentions that you might have to zone in to Upper Jeuno with Signal Pearl equipped to get that quest. For level break 60-65 according to wiki you only have to have Signal Pearl in your inventory/mog satchel/sack, but your g/f could try zoning to rendezvous point and zone back pearl equipped. As Raisst said you have to talk to the taru Ratoto to flag the quest. Try zoning to rendezvous point and back with pearl equipped for 50-55. I really dug into that one and could find nothing that would stop you from getting the quest unless your adventuring fellow bond is not 35 or you didn't complete A Pose By Any Other Name. You could check your quest log to make sure you completed the quest for adventuring fellow bond "Past Reflections". This increases bond from 30 -50. Blighted Gloom, Blessed Radiance and Chameleon Capers are also adventuring fellow bond quests and need to be completed in order to get the level breaks done for higher levels.

Hope this all helps.
