During my survival playthrough have noticed that there are no caves in my infinite Minecraft World.
Caves are underground areas where mobs are able to spawn and often include water and/or lava streams and valuable minerals. I reached the bedrock level and could only find lava but no open areas where found.
Some websites claim that the 0.9 Update included "optional" caves.
The map is an infinite world generated in Minecraft PE 0.10.
I'm unable to find an option to enable caves in Minecraft PE 0.11 for Android.
Are caves uncommon to Minecraft PE due to memory constrains or this is a bug?
