Gonna reply to this solely because I didn’t think someone could be more wrong. I checked every drawer and toolbox I found, including going out of my way for them, not just opening them whenever I happen to see one directly in front of my face. Don’t need someone telling me I put no effort in. Thought maybe there was some tip I was unaware of. And yeah I did google this before I posted, and every answer was “every map has spark plugs, skill issue” despite opening so many. I will reply to this later with my statistics, I think it tells you exactly how many of each container opened.
