In my GTA 5 online stats, I can see I played 113 of 201 missions. I played every contact mission from Lester, Ron, Martin, Gerald, Lamar, Simeon and Trevor.
If I press start and host a game, I can only host missions I completed.
Every mission I request by phone is a mission I played and that since 5 days. So I'm wondering, how do I play the other 88 missions?
