Affects Version/s: Minecraft 18w20c
Fix Version/s: None
Environment:Windows 7 SP1 64bit
Java 1.8.0_25 64bit
I'm currently playing a world created in 18w16a and then converted to 18w20a, b and c.
I can't tell at which one of the 18w20 patches this started happening.
Basically, during the night, aggressive mobs only spawn underground.
I'm in a mine at y = 11, and mobs spawn here during the night.
As soon as it becomes day, zombies and skeletons start to burn like they would do overground.
Nether isn't affected.
I also noticed constant daylight in a little cave whit no torches that served as a mob spawner, and now it's completely useless.
Seems like a world conversion error.
