In the past two months of playing Minecraft Bedrock Edition, I have not seen a single Pillager patrol in any of my survival worlds. Considering all of the griping from Java Edition players, these events should happen regularly. I also managed to locate an Outpost a few hundred blocks from my base, and it loaded with several generated Pillagers. However, after I killed them, they did not respawn around the structure like they should in Java Edition. It seems like the whole natural generation of these mobs is bugged.

This issue also affects Nintendo Switch Edition; I have not seen any Pillager patrols in it either. Therefore, I believe this issue affects all of the Bedrock "Village and Pillage" update, not just an isolated incident on my computer.
