I threw together this script to find rogue morphs that have been turned on, that shouldn't be on. Basically, load the default male or female character into the scene, and select it. Under normal circumstances, the base character shouldn't have any morphs turned on.
It can also be used to dump a list of all "currently used" morphs, but it won't dump all "currently used" properties, as it only searches for morphs, and not something like on/off boolean properties. I originally wanted a script to list all "currently used" properties, morph or not, but I didn't find such a script in my searches. But, I did find this one.
What to do if you find a rogue morph? Still figuring that out. If the morph belongs to a recently installed product that doesn't belong to Daz, then it definitely shouldn't be turned on. Might have to edit the data file to set the morph default value to zero.
