The textures are applied and working when I save, after the crash, the textures are no longer there. These are mapped textures from Daz objects that have been imported through native importer or transposer2.  I've tried it both ways and it doesn't seem to make a difference which I choose.  The only thing I can find in common is that the "dropped" textures have transparency applied in some manner. If I don't save the textures continue to be applied until I finish the image or until Carrara crashes, whichever comes first.

I understand that if it crashes while saving, then nothing is going to be right, but if the save is successful, and the crashing occurs during rendering I would expect the textures to still be working if the object is still included in the scene.

I don't save them internally, as I have been told that makes the file bigger and more apt to crash during saving, but my link to Poser is correct and as I stated, no files were moved. 

I've been dealing with this problem off and on ever since I got Carrara 5 Pro. It seemed to get better for a bit, but now it's worse than ever and I haven't changed anything on my system or with the program. I still haven't heard from the first bug report I sent in, so didn't see much use in sending in another one. Only difference now is I've used Carrara enough to learn clean out unused objects and shaders,  and to keep a check on settings after crashes occur.
