Heist - cant unlock my masters

HI
i cant find all of my masters. those green initiating contracts just dont drop

i am missing five of my masters.
help

The green contracts dont matter. You just need to run a heist with a specific member and they will bring their friend along.

The poewiki shows the chain of who invites who.


Players may hire various rogues to assist them in heists and grand heists. Players may select which rogue performs which job and they will accordingly appear in the heist.
The order to unlock new Rogues is as follows:

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.

ooh. thats how it is. thanx alot

Also, those green contracts for the other rogues don't drop until after you've unlocked the rogues.
