Pit of Clown Fiestas

After the launch of Battle for Azeroth's patch 8.0.1, the Pit of Saron experienced a large amount of bugs, documented in the list below. Most notably, the slave NPCs could use the appearance, quotes or flavor text from other, unrelated NPCs, and bosses from other instances could spawn inside the Pit. The issues were fixed with the July 24th hotfix.

Bugs

 * Alliance Slaves would rarely turn into Balnazzars, complete with aggro and death quotes. They could be killed and would drop loot from his actual loot table but curiously retained their slave IDs. The Balnazzars had their usual spells and would occasionally stun all players present in the instance. This increased in frequency, as the number of nathrezim grew.
 * Alliance Slaves would have the gossip lines of Magister Duskwither.
 * Alliance Slaves would yell various boss quotes from Blackwing Lair.
 * Alliance Slaves would wield weapons from NPCs whose lines they are speaking.
 * Alliance Slaves could appear as tigons (using their DisplayID).
 * Alliance Slaves would sometimes do empty yells and says.
 * Damaged Necrotic Shards could spawn in place of slaves.
 * Spectral Death Knights and Spectral Trainees could spawn as the minions of Horde Slaves.
 * Running in and down the ramp, could cause every mob reachable before the first two bosses to aggro.
 * When freed, slaves might switch between running back and forth and idling about.
 * Some slaves would simply despawn randomly, leaving behind their ball and chains. Clicking the balls would then free a random nearby slave instead.
 * Slaves would sometimes be replaced by Unrelenting Trainees.
 * Horde Slaves could have Bile Sludges as their minions.
 * Alliance slaves would sometimes perform a teleportation animation only to continue working.
 * Alliance slaves would sometimes become towards Alliance players.
 * Alliance slaves would sometimes have empty lines in Orcish.

Slave quotes and emotes
