In one area of the map it was lit every six blocks, in a grid.  In another, it was lit every four, also in a grid.  This should not allow hostile mobs to spawn.  Collectively we have logged tens of thousands of hours and can say with confidence this is a new bug.  Perhaps there are dark areas underground and the change in coding is allowing them to spawn at the surface level instead, but that doesn't explain passive mobs spawning in off-limit areas or slimes spawning in the wrong biomes.  No, this needs to be fixed.

Please confirm.  We are experienced Minecrafters and can confirm this problem on the Xbox one.  The inability to keep specific areas safe is practically game-breaking (e.g. villagers keep being killed).  We can also confirm spawning issues with both hostile and passive mobs.
