So on PC we have editor loader mod, or we can add in through one of the c files to be able to place structures/p3d objects to the map. On console through Nitrado we are only able to use JSON object spawning which reloads the builds on restart, essentially resetting them to stock placements, what everyone is saying for the nasdara assets on the rebuildable structures is that there isnt any persistence for them when placed by JSON within the objectspawner arrays that we know of, there is item persistence when those are picked up, and slight vehicle persistence but those get removed as well on restart, items are the only things that gain CE persistence when placed by JSON object spawner system
