Hasn't happened before and I'm unsure what it might be. My prime suspect is the Less Knockback feature in Phitt's Phighting Phixes, but that's just a vague hunch so I don't want to post in that thread.
1. It's recently added which seems to fit in with the issue being new.
2. Also, I've used it for a while w/o issues but changed the Less Knockback settings in the ini to vanilla just before loading the save in which it happened.
Should I do a clean save after changing the ini? Or wait for a respawn? Seems unlikely. Or is it something entirely different? Any ideas?
