possible *spoiler* but only at the the start. i am at 10% completion and at the generator room of the first broken ship. i turn ship on powers up activate it and then go to elevator and go up to the top and ellie and 2 survivors are standing there not moving. i go back down and kill the tentecales that apperard when i got to the top and then go back up and 2 survivors are missing and now just ellie staring in to the distance no interaction i've closed game and restarted the mission 3 times all cheats off and its still broken or am i missing something. sorry in advance for grammar spelling probs.
I think it's the easy kill option. It messes up the script quite a few times and keeps you from progressing. You could savely add the "use only when needed" warning in the trainer helpfile.
