Hi I have this exact issue. I'm playing via gamepass on PC, no mods. Unfortunatley I can't say if this happened before the v1.1.0 patch because it's my first playthrough and I only promoted them to lords after it
Anyhow so far I've had about 3 companions that were promoted to clan leaders dissapear for no reason.
I do have a save file though that is just before one goes awol, she is in my army and dissapears as soon as it is morning - tried a lot of things to prevent it from happening but nothing worked.
I would be happy to send you this game save file however it is not located in the Documents folder as suggested by the guide @

I Imagine this is due me playing via gamepass and it is instead hidden away somewhere in microsofts derpy format. Say for example this folder
C:\Users\%userprofile%\AppData\Local\Packages\TaleWorldsEntertainment.MountBladeIIBannerlord_mk53pm3ay0384\SystemAppData\wgs\000901FEB9FEAA2B_0000000000000000000000007587F9EB\C00B565AFAFE49EAB8AFF8C8FB0962C1
Very user friendly!
Can you confirm this the correct save location for gamepass and is it ok to send the suspected save file? (I can sort by date modified to narrow down which bunch of numbers and letters the save file is.
