I was playing around day 50 when after you meet Shanice with bot at the abandoned factory you go for a walk and bot disappears which leads into you getting kidnapped or something. I would like to continue my save but I'm not sure how far back to go because i do not know what causes this.

I don’t remember exactly, but it seems like you need to have a high relationship with the robot (500+ not sure). Then when they want to kidnap her, you need to stay with her and she will help fight back

P.S. if I understand correctly what event you are talking about

Do you remember that event in witch priestbot ask you what you discussed with the nun?  Tell him

I think you need the churches good ending for it

also I did all this but now my bot isn’t getting kidnapped, and instead big daddy hurt is ignoring me but then again I did tell the church about him so that may have changed it.
