You rescue Hana, hear enough dialogue to assume the job is done, and leave The Rescue feeling clever-then Kurai has nothing useful to say and Contract: The Twins refuses to show up. That scenario explains most POE currency searches around the Vox Twins in POE 3.29, but the real issue is that two different progression systems are being mixed together. The Rescue is a scripted quest step; Contract: The Twins is a rare Heist contract found through later rewards.
The Rescue Has a Missable Finish
Rescuing Hana is only the visible part of the first step. After the objective updates, stay in the area and let the Vox exchange, dialogue, and alarm sequence finish before taking the exit. Leaving early can make the contract look complete while the next Kurai trigger remains unresolved. From what I've seen, this is the most expensive mistake because players then spend several maps searching for an item that cannot solve a dialogue-state problem.
Enter The Rescue from Rogue Harbour.
Rescue Hana and move into the Vox section.
Wait for the dialogue and alarm sequence to finish.
Escape through the contract exit instead of abandoning the area.
Return to Kurai and check for new dialogue or an updated objective.
Why More Maps May Not Help
Contract: The Twins is a unique contract tied to Kurai's Heist storyline, not a guaranteed reward after a fixed map count. Available contract information places it at level 83, with level 5 Lockpicking and Kurai involved in the required Heist progression. It can appear from Smuggler's Caches and reward chests in Heists or Grand Heists after the necessary Kurai contracts are complete. That means a dry streak is frustrating RNG, not proof that your character has stopped progressing.
Farm With a Plan, Not a Panic Loop
Once Kurai has advanced, keep opening Smuggler's Caches during normal POE 3.29 mapping. Don't throw away a good Atlas rhythm just to chase one contract; collect blueprints, ordinary contracts, map completion, and currency at the same time. Also check Heist storage carefully, since unique contracts can be missed when you only scan the ordinary contract list. I could be wrong but, in practice, the biggest time saver is writing down your current Kurai objective before doing another batch of maps.
Your situation Best move Why
Kurai has no new dialogue Review The Rescue The story trigger may be unfinished
The Rescue is confirmed Open Caches and Heist rewards The Twins is a rare drop
Trade league Consider buying the contract It cuts down the waiting period
Challenge progress is missing Check area level and boss kills The encounter may not meet the condition
Don't Reverse the Quest Order
If Contract: The Twins appears before you have checked Kurai's story state, resist the urge to rush straight into it. Give the contract to Adiyah only after The Rescue is properly settled, then enter the encounter and defeat Vic Vox and Vinny Vox. Community reports describe awkward dialogue or turn-in behavior after the unique contract is completed too early. The exact cause isn't always obvious, so the cleanest route is simple: story trigger first, contract second, bosses third.
Build Preparation for Vic and Vinny
The fight asks for more than a high tooltip DPS number. The twins shift between melee and ranged pressure, reposition as their life totals drop, and fill the arena with fire damage-over-time effects and frost hazards. When one dies, the survivor becomes much more dangerous. Some builds should lower both bosses together; others can burst one down and handle the empowered phase. Keep moving, maintain damage while repositioning, and bring a loadout that can survive sustained arena pressure rather than relying on a single clutch burst.
Your Best Route From Here
For self-found characters, finish The Rescue correctly, confirm Kurai's response, then open every Smuggler's Cache you encounter while continuing normal endgame mapping. Trade-enabled players can seek the contract directly, but buying it doesn't repair an incomplete quest stage. Check the area level before entry, verify that both Vox bosses fall, and use another eligible challenge option if the fight doesn't suit your build. Spend your Path of exile currency only after the quest state is clear, because no amount of extra loot fixes an early exit from The Rescue.
