Hostile mobs sometimes spawn in a single condensed area, which can both cause lag and does not create enjoyable gameplay. Attached: Created a new world, teleported to a stronghold in that world, and about 30-40 mobs spawned in a small space under the ocean.

Was afraid of that. I've seen it only once before in this snapshot and it's tough to recreate since mob spawning is pseudo-random.

Is this still an issue in the most recent versions (currently that is 1.10.2, or 16w42a) of Minecraft? If so, please update the affected versions and help us keeping this ticket updated from time to time.

May or may not still be an issue, but have not been able to reproduce this since this first instance since it's so sporadic and randomly occurring.
