I'm playing the mission now and there is a really weird bug: If I drop a body in line of sight of enemy ai (Roughboys in this case), they immediately start searching and after a short while run to that body. This is in complete darkness (lightgem is black). They shouldn't be able to see the body. I am playing with the 2.11 dev edition, so I should test it with 2.10 as well. Edit: Same in 2.10
