Leave it Where it lay fail

So I was just attempting the Leave It Where It Lay achievement. I was at the part where your in that huge room with the bridge, the room who’s door blows up when you try and open it. It took me about 2 hours to get to that part after dealing with the waves of horse -Yoink- from Covy’s and flood AND sentinels. So I go to press the button to open the door to the next area, but I wasn’t aware of an assault rifle laying right next to the controls. So I open the door but ALSO pick up the assault rifle… I probably won’t play CEA for a few days after that. Anyone else have a similar experience?

I feel ya, had no problem with that achievement but have done that with games in my life. One that comes to mind is GTA III, that mission “Bomb da Base II” was just impossible and hard as F***, so I stopped playing it for a moth and a 1/2.
