I am installing smart switches in my home. I have this 2-gang box at the top of our stairs, where I am doing a virtual 3-way setup for both switches. One powers the light on the stairs, the other the hallway at the top of the stairs. A few things:

• This box has no live wires since its the other side of the two 3-ways (I have tested this by disconnecting all wires from all switches and checking for lives).
• Each of the boxes is on a separate breaker. It has TWO sets of neutral pigtails in the back. This is the correct setup, but its possible the neutrals where mixed up during the original wiring of the house.
• Each set of romex wires is connected to another set of romex. None of them criss-cross (except the grounds).

Now, here is my odd behavior and my need for assistance:

After wiring the two virtual 3-way setups (Option 2 from this page) everything was working fine. I was also planning to switch out the fixtures, so I went back and turned off the breaker for the hallway, but the smart switch for the hallway was still active (LED is on, I can see it on homeassistant). Now, I am thinking the original wiring mixed up the loads in the box with the incoming wires and the two neutrals for those breakers have been connected...anyone have thoughts on whats going on? is the solution here to basically swap the incoming 3-wire load romex?

**Solution: **
I am not 100% certain the cause of the issue. It is possible I mixed the wiring up when doing the virtual 3-way, but I basically followed the advice here and started from scratch. I traced the travelers from each of the main boxes and connected them to the appropriate load and completed disconnected the 3-way part. once I had the right load on the right travelers, I then setup the virtual switches wiring off the black wire coming with the traveler. Lastly, I ensured the neutrals from the two romexs that had a traveler+load where pigtailed with the virtual switch. took a bit of time, but felt this was the easiest way to not spin my wheels too much. Appreciate the advice, if anyone really does want, I can put together a diagram (on paper 😉 )
