Missing button prompt text issue

[towman]

I don't think it does anything besides what the narrator at the end says?

Actually you get an extra task, land on a field close to Johnson, pick him up and take off, leave the area, I guess for extra points and a different closing narration of the mission.

Already figured it out, right=no, left=yes, for future reference (I think there are more missions with multiple choice actions). Anyway, I was just wondering if this is something unique, result of some specific setting combination or just a generic bug for the PS3 version? Noone else had this problem?
