Character mistake: In Pitch Black they established the system they crashed in (M-344/G) had 3 stars. Jack stated it when the 2nd sunrise started, and the solar system model also had 3 stars. In this film when Boss Johns starts asking about M-344/G he says it is "a backwater system with 2 suns and 1 habitable planet."
Other mistake: The trip back on foot from the nodes for Johns was way too fast, and he likely would not have had enough ammo to handle the entire trip back. From Riddick's perspective, John's left, he cauterized his wounds with some explosive debris, fought several creatures and then ascended the hill continuing to fight creatures. By the time he hit the top of the hill, Johns had made the entire trip on foot, which was long by bike, had Dahl join him, locked in the node, and piloted the ship back to Riddick.
Continuity mistake: When Santana begins to "spit noise" to intimidate Riddick, the camera moves around him and we can see the station and some mercs in the background, one of which is Falco and he is alone, but then the shot changes and we can see Vargas next to Falco talking to him. The shot changes again to Santana and when he is lifting the box, we can see Vargas approaching Falco in the background.
Continuity mistake: When Santana is trying to open the locker, after he enters the third "click", he talks with Johns and looks at him, putting his back to the locker. In one shot Santana is near the locker, but in the long shot, he is further from it.
Continuity mistake: When Santana is going to open the bloody written locker, he takes the key off his neck, but when he puts the key in the keyhole, it's around his neck again. Some moments later, when he is talking with Johns, the key is off his neck again.
Other mistake: In the scene where Riddick, Johns, and the bad goatee-dude go on the "bikes" to get the missing engine parts (nodes), they travel quite a distance (about two minutes of movie time). After the "bikes' get shot up and are no longer usable, it's not that far at all for Johns to get back. In fact it's just a few steps, and monster free too. (01:03:00 - 01:07:00)
Other mistake: Matthew Nable plays "Boss" Johns, the father of William J. Johns in Pitch Black, who was played by Cole Hauser. But the two actors are only a couple of years apart in age - Nable doesn't look anywhere near old enough to be Hauser's father. Would have made more sense for him to be an older brother.
Suggested correction: We're just not shown the remainder of his trip back to the base.

Riddick cauterized his wound, fought off some creatures and made his way up a large hill. In that short period of time, Johns walks back the distance that took 2 minutes by bike, installs a node, gets Dahl, starts up the ship and flies back to Riddick. The original entry is valid.
