What were the last several missions you did (in order).
I tried to look on your rockstar social club page but you are "not sharing game stats".
Also are there any other story missions available.
On my game, these were the missions leading up to the Bureau raid-- perhaps one or more of these is required to unlock that mission.
The Ballad of Rocco
Cleaning out the Bureau
Reuniting the Family
Architects Plan (this is a prep for that mission I think???)
Bureau raid- Fire Crew
I don't recall if there is any other "preparation" required for that mission.
