Whoa, I didn't know the explosives were so powerful! Because my house was far, far away from the junkyard and I like free scrap, I used buydebug to place four large piles a bit away from the house so as to not accidentally detonate something in the house.
So, I place an explosive on one of the piles, and obviously they all blow up. A split second later, the entire house blows up - everything that could be ruined was ruined. I had to replace every single furniture piece aside from the large hot tub, the inventor's table, and the car, which somehow avoided the explosion.
So yeah, I'm not gonna try to do that again.
