Today I saw nether hounds spawn on half slabs in nether. I've seen them spawn on top of a chest before. I've also seen enraged spawn in very well lit areas and on top of glass or in water. Neither of these mobs respect the 24 block spawn requirement either.Please, please correct this. Being able to secure an area is core to the survival experience. Changing difficulty to level 1 doesn't help against nether hounds and what used to be a safe nether hub before 1.8 is now the cause of many deaths, of which theres nothing I can do to prevent the spawns (half slabs or glass wont stop them...).
