(fixed) (SE) Some animations work, others don't?

[Adeladen]

I only have leito animation packs installed and some of them work, some don't, it doesn't seem to be the fault of any one pack. Sometimes they start and work just fine, but most of the time they just teleport a bit, most of the time into each other, and stand there doing nothing while sound effects play.

I ran FNIS with HKX File Compatibility check and Skeleton arm fix, no errors, worked just fine. I did the animation registering and cleaning and what have you, nothing seemed to make a difference. 
My load order is FNIS Creature pack, FNIS Spells, FNIS, XP32, Fair skin complexion, CBBE, CBPC, The joy of perspective, SOS, then poses and animations and sexlab stuff in an order I haven't really paid attention to.

Edit: reinstalling sexlab and running a clean fixed it.
