I know I'm a little late to the convo, but did the mod issues with the updates ever get resolved for you guys? The mod linked in the op didn't work for me in version 1.10.3.4, and I'm not exactly confident enough in my skills to troubleshoot it alone if I don't have to.

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.
