Tropic Thunder (2008)

Plot hole: In the scene where Speedman and Lazarus are discussing their acting and Lazarus tells him to never go full retard. It shows these two leading the group, however they stop and talk for quite a while, and the rest of the group are nowhere to be seen until Speedman and Lazarus start moving again. The group finally caught up with them. If at this time, Speedman was still leading the way with the map, how could the group even find these two after being left behind enough distance that this conversation could take place?
