I feel like you're either over-aggravated or a troll; you are angry at the Mojang team for releasing a version with bugs, but the point of a pre-release is to release a version that probably has bugs so that the community can find bugs better.
@neko it was over 600 blocks from the nearest village, not near an outpost, and to the best of my knowledge pillagers only spawn near those two places
This is not a bug; mobs will not naturally spawn in the Void super flat preset. I believe this has to do with the biome, "the_void".
