Giana is missing from Heist List !

I haven't met Giana up until now, i've made almost all Heist Quests (including Lady Kurai) and unique contracts started to drop from the Cache, but still No Giana! is she removed from the new league??

Try doing a Vinderi contract, he should bring Giana.

There's an order for unlocking heist members

Tibbs, the Giant -> Tullina, the Catburglar -> Nenet, the Scout.
Karst, the Lockpick -> Huck, the Soldier -> Niles, the Interrogator -> Vinderi, the Dismantler -> Gianna, the Master of Disguise.
Isla, the Engineer is the only starting rogue who will not unlock any new Rogue if you keep running contracts with her.

But i did finish Vindari's quests and she didn't appear with him, is there a way to reset his quests and do it all over again?

Try doing just a regular contract with him. He can do Demolition, trap disarm or engineering. If you don't have one, try Whakano, he sells them in his shop for 1 chance orb, and might have one of those types. His shop will update by levelling.

OMG it worked!!!! ty so much <333333
