I did the same thing one thing that did help was using up the top About Land go to objects then click on show all abjects will have a white edge so anything in the ground will show up or the shape of ur object will show if in another prim etc. One thing I did learn was with the amount of prims I have used on my parcel now if I play around with prims and scripts I am not sure about I go to a sandbox that way they wil be returned either way.
Good Luck
