Today, I tried the Iron Mines of Moladune (sp?) mission 3 times. Two of those times, the mission was "bugged", and we were unable to finish

What happens is, when you finally reach the end of the mission (to the place where Markis should be), he isn't there. Everything else is normal; the jade armours come out and start beating on you, all the other units are there, etc. But Markis is nowhere to be found! For those who are not aware, you have to kill Markis to finish the mission

Markis was even at the start of the mission running across the bridge.

As I said previously, it only happened twice out of three times. If I remember correctly, the only time it wasn't messed up was the time where we actually stopped to infuse; the other two times, we ran the path to respawn at the cinematic, but didn't go and actually infuse our armour. I assume this was the cause of the problem.
Has this been happening to anyone else? It's a really annoying bug because it isn't know until the very end, and it wastes everyones time.
