Then something probably happened to solve that problem, if the world isn't falling apart don't ask questions! You'll made it fall apart by speaking the question!

In all seriousness.... there are many things that might've happened, I mean... didn't Yoruichi say it was possible to fix the problem of Soul King death when making that barrier?

I know it was due to Mimihagi being around, but considering Kisuke and Mayuri were both in that palace anything is possible, after Kisuke was freed from the Deluxe Donuts Sphere of course.
