If it crashes you got a bad rev, you should always compile 1.0 on your own computer, since it will make it work alot better, (Look at the first post).
I use this one for testing, and on the dedicated I run one ive compiled myself.

I downloaded the one from printers github, got crashes etc, when I tested the rev 915, it worked without any problems, no crashes etc.
Reinstall the datapack, I diden't change any major things in the npc files, or do you have any errors in the console?
