AAF not starting on previous save.

[KKSlider]

I had AAF and associated mods working perfectly, at some point however (pre-update), something broke. 

 

I've used Simple Downgrader on my game files to enable certain MCM mods again, as my game auto-updated.

 

Currently have F4SE v 0.6.23 working fine. AAF is v Beta161.1.

 

I'm able to get AAFs menu to pop up, and am able to play animations on a freshly started save- but not on my main, the one AAF initially was working with.

I use this mod that is able to run a check for AAF, and it displays as active on the problem save- but the menu hotkey does nothing. Similarly, the AAF aspect of said mod simply cuts to a black screen; no animations play.

 

Not sure where to start troubleshooting wise, so any advice is appreciated!
