• 🌊 A boss stays the mob it is. A zombie boss that sank and stayed under water turned into a plain drowned, and the boss was gone mid-fight. The same happened to a husk under water, a skeleton in powder snow, a piglin or hoglin in the Overworld, and a zombie villager someone cured. Now a boss stays itself, while plain mobs still turn. A slime still splits when it dies.
