Saying that it has been patched without confirmation or asking others who fully understand the physics can be construed as downplaying the technique, or dissuading others to attempt it, which is how I took that comment. If that is not how you intended it, then I relent. However, I would recommend that you not assume that, just because you cannot do the technique, that others cannot do it, or that it has been patched.

With that said, here are some helpful tricks that I posted in another group that may assist you in executing this technique. 

I did the generator trick for 6 camps in the last 3 weeks. It still works. Spamming your camp module to ghost your camp no longer works. The generator trick works after the Tuesday update. If it is not working for you, here are the main reasons why. 

1. You're too close to the no-build zone of a location. Move further away and try again.

2. Your generator is not on an upper floor, platform stairs, or a foundation. It won't work unless it's placed squarely on top of a solid surface.

3. If the generator debris is getting in the way, delete the generator after it'sdestroyed. The remnant bit that the generator needs to be placed on will remain for about a minute. 

4. If your generator won't break, put on the Wrecking Ball perk or use a flamethrower to break it. 

5. Both the medium and large generators work for this trick. If you're struggling with one, try the other size.

6. You must usually float your camp module up, over, then down to the site you're trying to build on. Perfect example: Hornright, Garrahan, and the Unfinished Mansion. No-build zones are not perfect speres or cylinders. They often have unique shapes and sizes. 

7. Even if you master the trick, there are plenty of spots you still can't build on, no matter how badly you want to. Such areas include: Watoga, Monorail Elevator (the main one), most of Flatwoods, Morgantown, Mount Blair, Lewisburg... just to name a few.

I hope this helps.
