Still unresolved issue as of 1.11.1 for Bedrock on X1. Haven't had any luck with copying game files or any of the recent updates.
Same issue, redstone lamp and torches aren't shutting off mob spawners in Survival. XBOX 1
Still occuring for me in Minecraft bedrock 1.10 on Xbox1.
Have 4 Dragons spawned. Anyway to reset this?
I have experienced this same issue with a world that is currently hosted on realms. In an ice biome, I filled/covered an underwater ruin with sand and gravel. I have found that the stones blocks act as a water source block. I have placed sand, gravel, dirt, and cobblestone next to each of these blocks and all the mossys stone bricks and chiseled stone bricks act as if they were water-logged.
