Andrew's Pose Player Constantly Resetting

I am so mad. I've been trying to get photos of my (very large) extended family for my legacy and after spending 20 minutes placing everyone and setting up poses... when I hit play they just reset back to normal and walk off. I even tried with autonomy off, but it still happens. Anybody know what might be causing it? I've been having a few other issues since the patch update but I don't think any of those are relevant. I have MCCC but otherwise I don't think my other mods would conflict. Everything is supposed to be updated (as far as I know). Help? ;_;
