Sexlab being slave - master punishes slave with whip, crash

[Istill]

Okay, it was always bothering me, ever since i installed mods from that framework i was bothering me why always, and only then, im getting crash.

 

It something like this, when master punishes with whip by using light attack everything is fine, but when he uses Heavy attack game crashes after he hits

[he uses double bladed heavy attack with both hands]. Any ideas what might cause this?

 

Another thing is when im using Death alternative and thalmor capture start/or being caputed by them, when im on the pillory[or whatever it is called] he punishes us for saying bad things, and when he uses sparks spell game crashes. Only place game crash.

 

I dont know what can cause this, game works fine, dont crashes at any other moments, only these two. DA crashes regardless of sexlab or rnd and similiar mods.
