Character Goes Invisible/Missing Texture In FP and TP View?

[Darkening Demise]

Don't know if this is normal or not. Never seen it before.

It seems to come and go...but the timing differs each time. So if I change equipment or use Sexlab it doesn't change. Not sure what is causing this. Would suck if I had to restart again, download files again.....done that too many times to continue.
