Vault Power Conduit is frustrating me.

[𝕊𝕙𝕒𝕚𝕕𝕠𝕟]

Yes I know about how the Vault Power Conduit work like a wireless power that transmits it though the connected structures.

So I extended that corridor. One side have the overseer room (with a VPC), the other a clinic. The corridor connects to a big atrium that goes till hit the wall. Big enough to have 3 floors, but I'm still working at the ground level. A VPC at the back of the atrium at the second level powers everything there. All lights working.
From the entrance of the atrium to the right is the residential. A corridor that divide 2 bathrooms, 2 rooms. At the top level I did the same. Just one VPC at the corridor power all rooms.

Now, here is where I'm loosing my hair. While the right side is domestic, the left will be utility.
I made a corridor that could not be go further than 4 parts cause it just hit that cave divider. The side that connects with the atrium and clinic I made a L shape 2 high atrium to be the "hydroponics", where I set all the garden plots.
But the power seem that refuses to connect to this side. If I set 1 VPC at the clinic back and another at the big atrium wall (bottom or top) that connects to the farmining area, I manage to light half of the room.
Already messed around with the utility corridor that I suspect to be the issue. I did some testing with the residential area by removing both (corridor w/ door) and that cut the power to residential. So that just taught me that walls type of structure don't connect the power.

Vault 88 has major electrical and power issues. You may expeience Crashing also when working with power.

I have found the following MOD to fix all my problems. It would likely fix your problems too.

I'm avoiding using mods for now. Pehaps later.
I end up fixing it, by creating a conduit set of tree parts to send energy through the wall and feed the VPC at the other side. Not clean as I want it, but it works.

But nonsense continue. Now that I can build all vault-tec structures outside, I decided to change my main settlement (Sanctuary), to something more compact. Because I already reach the building limitation and want everything to be more near each other.

So I create an 4x3 building using domestic prefabs. 1st floor Food & Drink, and other stuff that usually make the settlers gather around it at the end of the day, like the soda fountain. 2nd floor the other shops. Connecting floors outside, using the 2 types corridor stairwells. What was a B**** to make it snap together close and over each other.
Then, I though was nice to also add the power generation to this building. So I added a super reactor to the 3rd floos. And since its is 2x2, I had to set it close the front. The reactor seem that required 2 floors, so I changed the 3rd and 4th floors to atrium structures, what have prefabs for a 2 layer floors. Even so, I could not properly add any cealing or floor structure above the 2x2 reactor, with the exception of the top column for some reason (derpy Bethesda).
Connected the reactor power to a VPC nearby (3rd floor). Lights working at the floors bellow it. Set a VPC at the 1st to feed the soda fountain. And another VPC, outside the building at the 2nd foor, to feed my energy grid. Everything working nicely, and I was happy.

OK, so I though into making another building entirely of atrium (4x4), with the stair bridge going around it to reach each floor. 1st floor an open area (with columns) for the crating stations, because I know that settlers like to mess around it. 2nd and 3rd reserved for power armor, collectives, etc. And I decided to move the super reactor to the 4th and 5th, just remaking what I did at the previous building.
Now, here is where the problem begins, cause it didn't worked the same as the other building! The light at the 1st floor where working on both celling and wall only at the middle (2x2) and the side where the 4th flood VPC was connected to the reactor. OK, so I though was a matter of range. The energy was not even alive one floor bellow! Seriously, I set another VPC at the same wall side, right bellow it, and wasn't feeding a turret that I set for testing purposes. I changed the 3rd floor to the domestic prefabs to mimic the other building, and still not working! Weird enough, at the reactor level (4th floor), if I remove the VPC, set it again, and start the cable connection from it, it will spark, like there is energy already connected to it! o.O

OMG, I seriously can't understand this damn thing, if will not work the same way as did before.

Are you using the blue and red hallway bits to seperate sections?
My mum had the same problem in her vault. She didn't like that hallway pieces and just used "room" pieces to build the whole vault.
As far as I can tell its those blue and red ones that transmit the power because once I seperated sections and ran hallways through the place the power points worked in all the rooms. (the vault ones that snap to the walls). After that the whole thing worked fine with just a reactor near the big water pump.

Yes, as I said at the first post. Also did some testing will all types of prefabs to see how energy flows between them, and is just chaos. Sometimes works, sometimes not.

My last post for example, worked with a building, and didn't worked the same way with another. Might be related with the reactor. It snaped to the ground floor, the 2nd floor and 4th. But didn't snaped to the 3rd, 5th and 6th (celling) for whatever the reason. So I set it to the 2nd floor. Yet is not powering the other levels VPCs, except the "1st" and 3rd floors)
The ground level (1st floor) VPC is transmitting power even without the reactor not connected to the its same floor, VPC. But the 3rd floor VPC only got "live" after I connected it. Go firgure!

And I said that I couldn't set floors to the level above the reactor? Guess what, while it was at the 2nd floor, I could snap 2 pieces of floor above it. So what I did? I removed the reactor, filled the 2x2 gap, and snapped it again to where was before.

The snapping can be a headache with this game. Sometimes I can just make it work, by moving the entire building (holding E) to somewhere else, snap the piece that didn't worked before, and then move it back to the previous location.
And the energy grid, is less frutrating if you don't try to make it look pretty. =/

I think I figure out some of the issues with the atrium prefabs. As I found that my super reactor got destroyed by gods know what, I had to try to move it to top floor again.
So I though, pehaps the other floors are not really connected with the entire building, but just lined up. I shifted up one of the 2 high wall and that seems that created the connection. Even the reactor snapped to this new floor correctly. The 4th. Than was just a matter of fillling the gap with a wall mid and hanging floor.

There is also a chance after I left the settlement for a while, that something updated and fixed.
