As I created a second guardian (a hunter), I tried to skip introductory videos by randomly pressing buttons and pausing (pressing more buttons while paused), which worked on the Mars/Traveler video but not on the "Ghost searching car graveyard" introduction scene). I can't specify exactly when it happened, but I could not activate my Nav mode (holding your Ghost on hand to see mission waypoints), neither screen hints would appear on how to switch weapons or open chests, nor clip size. I was able to open the first chest, but i did not have the circle filling animation. I traveled to Last City and could not see button hints when approaching NPC's. Although I did not switch characters to see if it was persistent through character switching, restarting my PS3 made it work fine again. Since it was not show a error message (or it appeared and I couldn't see it because of this bug?), I'm not sure if you are aware of this type of bug.
