The bug

Pillager outpost spawning on top of desert temples. The desert temple is fully intact and doesn't have any of the outpost inside and it looks like the outpost was just set on top although it makes it difficult to raid the outpost as the only way to get in other than breaking blocks is to throw an ender pearl through the hole in the center of the desert temple.
