Thank you, that has fixed it for me.

That’s on the upper level, I mean the downstairs room which I have never had to enter with the agent but it says it is an IA phase. There is no info about it online that I can see.

Agreed. I just want a little farm area with a few defences. Nothing big, just a small farm.

What is that room on the lower level? I have never known how to get in there and I've played the story many times. It isn’t a main class mission. I have been in the game for several years and can never find the answer.
