I think that the final blow was our ending NAP status with them. They both deleted right after that. Your nukes had no affect
They went missing days before that. They declared, sent little incoming and then got bogged down with incoming. The ending of the NAP would have kicked them when they were down but Jen was pretty much doing nothing as it was. They had lost hope before this but no doubt it kicked the stuffing out of them for sure.
Also, our cat op which landed on her backlines in K29 knocked her down 450k points just before she barbed with over 1,000 cat nukes etc to land. She should have stuck around for that.
