New Pokémon Snap has just had an update that fixes a rather vexing bug…but what insight could this update have on the game overall? The update resolved a bug effecting one of the missions. Before, players performed the requirements necessary to complete Proud Warrior mission, it would still be listed as incomplete. This caused many players to become confused as to what they had done wrong. Luckily, this is now patched. So any players who were frustrated about this specific mission, feel free to go back and try it again!
However, if you have been trying to complete all the challenges, it is likely that there have been times when you thought the mission was complete, when it in fact wasn’t. Or alternatively, you felt like you did what you were supposed to, but nothing happened. This new patch may seed doubt that other missions are also bugged. Hopefully, if any are, they are patched soon!
