Restart your console?
First off, seriously? Second off, I'm a 45, it's been off multiple times since I could have had any mission from him.
I'm currently level 45, and I haven't gotten a single mission from him. If I call, the mission request is still locked. I went and visited him and Trevor at the point, and did the survival so long ago, but he just calls me and tells me people are attacking him or something. Anyone know?
When he calls to tell you people are attacking 'things'....that is just him promoting the Survival Mode jobs that are on the map.
I get that, but he should have sent me missions a while ago
