Upgraded map from 19w11b to 19w12a. Happened with hoppers leading into composters. Works fine, but initially gives error

Happened to me after upgrading from 19w14b to 1.14-pre1. I was going to the village and the game crashed with this message:
java.lang.IllegalStateException: POI data mismatch: already registered at ev{x=335, y=79, z=-417}

This is also happening to me after upgrading from 19w14b to 1.14-pre1. Issue occurs consistently, no more than a couple minutes after loading.
The game crashed whilst ticking entity
Error: java.lang.IllegalStateException: POI data mismatch: already registered at ev{x=-449, y=79, z=-273}
@unknown and @unknown: That's a different issue, see MC-147754.
Seems to be fixed.
