Confusious

OK so I found a rough solution to this. I tried to use the console to move both Rhonda and Tabitha outside after repairing Rhonda. This didn't work, at first, until I used the "enable" command for both of them. It seemed the game disabled both NPC's too early, but by re-enabling them and moving them together the game got itself back on track. No idea why it happened though.

So after some further testing, I've found that if I go to Tabitha's room BEFORE I interact with Rhonda, she is there and I can kill her. Given that both Rhonda and Tabitha disappear after I reactivate Rhonda, I think something is happening where the game deletes them instead of moving them outside for the good ending. Any suggestions on what could be the case?

So after I use Science to reactivate Rhonda the robot at the peak of Black Mountain, it immediately vanishes after I talk to it. As a result, when I go outside, Tabitha is nowhere to be seen. Even worse, if I then go up to Tabitha's control room, she's gone. The quest marker points outside where the reunion should be happening, but neither NPC is anywhere in sight. The mod list was posted using LOOT. If that's not helpful, I can put another one using NMM. I'd appreciate any help in solving this issue. Edit: Replaced the original list with a neater one, as suggested. I have not altered my timescale this playthrough. Rhonda is disappearing AFTER I repair it, and this is the first time I am visiting the storage room.
