Error while performing position scheduling for Person: Kiri Uzaki.
Object reference not set to an instance of an object.

It's the same with all the characters. What should I do?

How is the update progressing?

Remade the mod into modpack format (just drag this into mods and enable it), and fixed all the issues. Should work in 1.10.4.2.
