DLC Khan Mission broken?

[Th3Co0n .eXx]

In the Khan Mission after you slide down the pipe you enter a vent, after a short crawl a horde of rats apear. Khan tells you to light his torch, however, when i try to pull out the lighter when he asks me to i doesnt work. When i pull it out before that and i can light the torch, but the rats still kill me every time... I tried to stay right on his back or abit away from him, but nothing helps... Anyone else got this problem or knows a fix?

As for the lighting of the touch I am unsure, I did not have an issue.

But for the rats after lighting the touch, you just need to stay to the right wall while moving forward with Khan, to far to the centre or to the left of the tunnel and you die, just stay right. I hope this helps.

oh, ok I always stayed in the middle of the tunnel as far as i know, I'll give it a try, thanks!

EDIT: ok so that was indeed the solution, i just had to stay more to the right, thanks again :)
