Certain animations only work with NPC's

[FredandJeff]

So I recently decided to get back into modding Skyrim and I've ran into a weird issue.

 

So for testing I use the included matchmaker spells from SexLab p+  and it works mostly fine, animations play and things run smoothly. However some animations only seem to work on NPC's, for instance if I select two female NPC's and one male NPC it plays one of the installed animations without issue, however if I replace one of the female NPC's with my female PC it then gives me the "failed to load scene" error.

 

So basically, the animation is there

The game can load and apply it

It just does not seem to consider my player character valid for those animations for some reason.

 

I have gotten it to sometimes work by swapping sex with racemenu, doing the same configuration of male/female actors, then swapping back and trying again. This is however very inconsistent.

 

Any help would be greatly appreciated.
