Pillager outposts remove the ground around to spawn I guess. Probably something to do with the structure generating inside of a hill.

How to reproduce

1. Use the following command: Make the building load earlier than the terrain.

   /locate Pillager_Outpost
   

2. Use the creative mode to fly to the X: -1118 Y: 71 Z: 304.
