Are survivals glitched?

[based_gigachad]

Completing all challenges is one of the very last things I need for the plat in this game.

 

I can get the phonecalls that activate survival missions, and I've answered two tonight, let them finish talking to me without interrupting by shooting or stealing a car etc, and then just... nothing!? I'm accepting the calls but there's no waypoint coming up or anything on the map so it seems like they're bugged? I did a google search for this issue but I only got results about people not receiving survival phone calls at all or people having difficulty with launching the game.

 

Please, if anyone knows why this is happening and if there is a workaround, it would be great to hear. Otherwise I'll have to give up on this very shoddy remaster :/
