Still can't believe there is no resolution for this. Still I probably won't get this anyway as collecting things just annoys the hell out of me. If you miss one and can't remember what it was you're screwed and will have to start again (GTA IV
As mentioned it is probably one of the xbox only maps someone has missed a pickup in or it could be just glitched.
I mean I would help out with the pc version as I do a bit of modding and am alright at it and could look for them that way.
But can you get the maps from xbox from a download on pc or are they exclusive just to xbox?
