Chapter 6 Mission 2 Glitch

[fattness222]

I was playing the mission on the hard difficulty, when it loaded from the end of part one to the start of mission 2 there were no elfs to fight. When I destroyed all of the statues there wasn't a barrier, thus no way to end the mission without quitting. I took a couple screen shots of my wranglers stuck on the other side of the barrier.

I have tried to recreate the glitch, but have only managed to get it to occur about 1 in every 5 or 6 trys.

My system is windows XP SP3 32-bit.
Core 2 Quad 2.67
4GB of Ram (3.5 since 32-bit XP can only use 4GB of Ram)
9500GT 512MB of Ram

I am running all of the highest settings.
