I am currently stuck on the mission that has you getting the downed pilot and finding the safehouse. I have spent alot of time on this mission, but cannot find the safehouse at all. Can someone please tell me where it is, or what I need to do? Thanks...

Look around very carefully in the church. Follow your compass. Look for the glowing red button.

Hope this helps.

There's this altar and on each side there are red glowing buttons which you have to push (default key 'e') when you do this a secret passage way will appear...
