Abstract Method Error whilst Ticking Entity when teleporting New_Village structure from locate command.

This doesn't occur every time. Crash reports refer to an abstract method called whilst ticking entity. An Enderman the first time but the Player the second.
 
Description: Ticking entity
java.lang.AbstractMethodError: bxx$$Lambda$1063/1887459401.a(Lcom/mojang/datafixers/Dynamic;)Ljava/lang/Object;

This occurred in two villages on the same seed, 6860551933019121950, on a plains buffet world. After crashing the world fails to load crashing on ticking server with the same abstract method.
