Odd problem with SetLocation

K. This is rather weird. I am working on a system that will, when built, spawn a building quite a ways above the world, trace down and find the ground, then move the building there. I'm doing this because i just can't get the buildings to spawn directly on the ground, the are always floating in the air. Anyway, my problem comes after i've found the location on the terrain to move to:

Controller.Trace(HitLocation, HitNormal, TraceEnd, PlacedStructure.Location);

Works fine, TraceEnd is set correctly, Controller.Trace because this is in an Interaction. But here:

PlacedStructure.SetLocation(HitLocation);

doesn't work. I've tried it w/ both bUseCylinderCollision on and off, same problem. Is there something I'm missing?

Tried both True and False, doesn't work

Actually, I found out the problem. It probably was because I was inadvertantly placing the structure into the terrain. Thanx
