For people who are still stuck, there's 2 reasons, 1) if you started this morning and you logged out before they fixed the 3rd slot trigger, you now receive a different version of "Caught in the act" quest that Naoko won't recognize and neither would Jymmy.
For people who are still stuck, and started after the fix to the 3rd slot machine trigger, you spoke to the "switch" before finding all 3 triggers. A bug makes it so that triggering the switch before getting the quest "caught in the act" version A, will forever make Naoko repeat himself. And you will not be able to finish the quest on that character again.
Rumored 3rd glitch: All of the people in my guild that successfully completed the quest, has chose to "Buy the contract outright for 100,000 Zeny" from Old Lady Kroot. Not sure if this is coincidence but everyone who used the Bomb Steak option all got stuck.
Most successful way to avoid all potential glitch: Start quest on new character, give up on characters who are already stuck. Buy contract for 100K, do NOT touch the "Switch" on the airship before getting the quest "caught in the act"
All of the above are speculations but good educated speculations as my guild and I have been spending the whole day going through each of the steps carefully to compare all the gliches.
