Random characters help

[DeaDRocK]

so I've done everything in gta4 except the second and third encounter for Brian, the problem is that he's not spawning where it says on the random characters map. and i've the done first encounter at beginning of the story mode and now after i ve nearly done everything he's still not showing up!

could that be a technical problem or a bug?

Random characters seem to have the annoying (but coincidental) tendency to never be in their meeting point when you the player is looking for them. However when your driving through that area on your way to a mission the icon usually shows up. It’s worth noting that the characters only show up at certain points in the day, Brian for example should be at his meeting point (all 3 times) in the afternoon.
