Howdy Ho folks did a search but didnt find much about this and there's no sticky for it.
Brilliant game, nearly at the end of the legendary campaign then it's live all the way, anyway, come across a couple of glitches in the single player:
Mission 8 - Ander's Signal - Got stuck in the border of the map, couldn't get back out without restarting the mission, could move along the border but not back into the map.
Mission 13 - Beachhead - Shortly after receiving the Spartans Jerome decided it was all too much for him, he legged it through a hill, through the Covenant base (not over or around) and out of the map never to be seen again, the wierdest part was that I couldn't see him, the green circle and name tag were there but not his body, spooky eh.
Anyway, thanks for the great game :)
