Unfortunately this is not visible on the screenshot, but the disposable phone is active and issuing some colorful circle around it indicating that meeting is arranged.
But as you can see on the screenshot, even despite another suspect which came to a meeting is dead, the objective still uncompleted and will be failed on the exit.
So, I can conclude that this bug is not fixed. Or it was a fix for another bug.
Nevertheless, Arrange a Meeting prestige objective is still bugged
UPD: I made it work by arranging a meeting of target’s group, but the objective description says that just a meeting needs to be arranged, it does not specify that a target’s group meeting needs to be arranged.
So even if it works, it’s confusing.
Will test more on this matter
UPD 2:
On a second occasion I arranged a meeting and it didn’t work again.
Then I arranged target’s group meeting. And guess what?
Right. Objective isn’t compelete and failed on exit.
Seems like game randomly desides when to apply this objective.
So the bug is still here, nothing changed in the mechanics of the objective registering, it was like this before
