Ok, just an example here:

I have V4.2 with ++ and Lali's Bits as a standard custom character in the default position. She has AS's Desir Hair, I use the default 'Country' lighting to keep it neutral.

Sometimes the hair will pose when I add a library pose to it, sometimes it stays static and I have to delete it and reload it. Same for V4, sometimes the Daz morphs are there and everything works (expressions mainly, but breast morphs (up, down, in, out) and grasp morphs often don't) and sometimes there are a bunch of morphs missing. Most of the time the LB morphs are wrecked and won't budge, forcing me to load the default LB V4 figure and 'copy morphs from'.

 

I cannot tell what steps I'm taking which are causing it.

I'm running Win 10 Pro 32GB RAM Intel Core i7-4790K CPU @ 4.00GHz Nvidia GeForce GTX 1660 Ti
