Referencing center of class blue print instance

I’m trying to reference the center of each instance of a blue print class. When line trace hits the fertile ground, a coin is supposed to spawn above the location. What I want later though is to plant something in the ground, but I can’t figure out how to target the location correctly. My problem is that the coin always spawns at the center of the world, not the center of the class blue print that the line trace is hitting. How do I fix this? I’m getting the world location of “Box” which is a collision box that is part of the fertile ground blue print class that “Fertile” is referencing. I thought that would give me the center location of the actor.
