placed items arent shoing up ?

[pippa2]

hey everyone, i downloaded a mod but it required to use the console to get it, so i tried my hand at the geck, i load up diamond city and place it infront of the player house, i save and push to pc, then launch fallout 4 and activate the esp in the game, it relaunches, and i go to the location and its not there, i tried this with just in game items aswell as modded items, i only select the mod and the main fallout 4 file, but nothing seems to be working ? am i doing something wrong
