I've come across two different glitches with the brotherhood of steel quest line.

The first being the quest tactical thinking. In it a detonator pack is supposed to be placed on a wall for you to activate and carry on. In my game the pack doesn't appear leaving me unable to proceed. I tried loading a save to before accepting the quest but that didn't work I decided to pursue the institute quest line which seemed to let me skip that quest and move on to ad victorium.

Which leads me to my second glitch. When liberty prime is activated for you to follow he just stands about sometimes trying to move. I looked at some youtube videos of people doing the quest and saw that the area he is in has a section of barricade for him to pass through but on my game it is still enclosed. Tried fast travelling out and beck in before activating him but got nothing.

Dont know how to fix this without creating a new save. Has anybody else come across this? the first one seems a bit more common and is similar to the end of the line quest glitch.
