Steps to reproduce

1. In creative mode, wait for a pillager patrol to spawn naturally.
2. Spawn a villager near the pillagers.

Expected result

The pillagers attack the villager.

Actual result

Results vary!

• Sometimes the pillagers attack the villager.
• Sometimes the pillagers load their crossbows then aim at the villager and freeze.
• Sometimes the pillagers ignore the villager.

Note

It is possible to reproduce this in survival with the pillagers targeting the player, but it's easier to do with villagers in creative.

Test world

The attached test world contains a repeating command block that teleports all pillagers to a central spot for testing. The command block can be turned on or off with the lever to allow the pillagers to stand on their own 2 feet. The named pillager captain already present had spawned naturally and had previously attacked villagers and wandering traders that were then killed by the player. The pillager's shooting range is roughly marked out with stone.
