I recommended...
opening the blocked vents (did it while I was in there),
fixing the dryer vent to the exterior,
remove all the wet insulation,
mechanically ventilate the crawlspace with fans from the garage and install a proper vapor retarder,
reinstall dry installation...
Moisture was mostly condensate from the HVAC ducts. All the damaged batts were within 3 or 4 feet of the ducts...
