I'm currently deleting all the Bridgeport Street Lights that are scattered around Bridgeport and replacing them with Actual Streetlamps from the Island Paradise expansion pack. But I've run into a big problem.

The Bridgeport Street Lights can't be deleted in Edit Town which complicates remembering the exact position of each Street Light so I can drag and drop each of the Actual Streetlamps in the exact positions that were previously occupied by the Bridgeport Street Lights. They can only be deleted by nuking them in Live Mode. If I nuke them in Live Mode, it makes it a lot harder for me to memorise the position of each of the Street Lights. Which will make it a long and tiresome task.

Is there anything that will allow me to delete the Street Lights in Edit Town rather than Live Mode? I have tried marking the spots of each of the Street Lights, but that strategy failed, as when the time came to nuke the Street Lights, I ended up deleting the objects that I was using to mark the Street Lights, and not the Street Lights themselves. Even though I didn't put the objects too close to the Street Lights.

Not that I know of; although there are NRaas mods which you can use to nuke all objects of a type through live mode. Calling @Igazor for that!

Yeah, but I don't want to use that. Because then I won't be able to memorise where exactly I have to place each Actual Streetlamp. Also there are going to be some Bridgeport Street Lights that I will want to keep, as there are some Bridgeport Street Lights that are located in places where I won't be able to place Actual Streetlamps. I only want to delete the ones located in places where I will be able to place Actual Streetlamps.

can't you place the new lamps where the old lamps still are, then delete the old lamps through live mode, then scoot the new lamps into the right position if they're not already exactly where you want them? that way you don't have to remember where they're supposed to go. i haven't messed around with editing neighborhoods in a while so i don't remember if there's a limit to how close you can place objects to one another.

As of the 25th December in the evening and the 26th December in the morning in New Zealand time, I have displaced all the Bridgeport Street Lights with Actual Streetlamps. Thanks to using fence posts as blueprints. Placing the Actual Streetlamps where the Bridgeport Street Lights still are and then deleting the Bridgeport Street Lights with the Object Stats option from NRaas' Master Controller mod is possible. It is what I did with the last couple of Bridgeport Street Lights. Since I wouldn't have been able to safely delete the last Bridgeport Street Light or two with AwesomeMod's Nuke option since it would have accidentally deleted one of the gem spawners.

Unfortunately it doesn't seem like it will be possible to displace the Well Kept Municipal and Unsightly Urban Trash Cans with Clean Town Trash Cans. At least not with the same methods. As they aren't clickable objects, and because they have been locked from being moved or deleted, getting rid of them is going to be harder, if not impossible. Unless I find a way to delete them with Master Controller. But they don't seem to show up on the list of objects to flush with the Object Stats option.
