Confirmed. Upgraded my SMP server to 14w20a. Difficulty is set to Hard. Mobs are not spawning under normal spawning conditions. Mob spawners are working as normal.

Yes. I see the same thing. Spawners (and /summon command) work, but naturally spawned mobs are disappearing immediately.

Confirmed. They appear and disappear just like trying to use a hostile spawn egg on peaceful.

Just out of random curiosity did this affect already spawned entities? Did villagers get atomized? Did paintings fall down? Did pets go to a nice couple who live on a farm upstate?

I know it's fixed; but this existed VERY long time way before the official release of Minecraft.

Fixed in 14w20b.

I just updated my server from 1.15.2 to 20w06a an i noticed while some mobs spawn an stay spawned in, quite a lot of them appear to spawn an despawn instantly as shown in the brief video link. https://puu.sh/F84pl/b275218ae6.mp4
