What info? If you talked with Cassedy and got the quest for the peace route, you just have to take the ship back to the beach of the luminous order, where the next step automatically triggers.
If you have the quest, it should automatically trigger the next step when you get to the area I showed in the screenshot.
Unless you're on android, you could send me your save file to Naughty-Netherpunch@web.de so that I could check if you have some sort of bug. The saves are in the www/save folder. I only need one .rpgsave file with the save slot number in which you have the issue.
