To do: change version range to the preupgrade postupgrade range stuff

Beta 1.8 added the MapFeatures tag, which allows the player to choose if they want structures to generate or not. When you update to Beta 1.8, this tag needs to be added to your world, and consequently set to 1. However, if you update to Beta 1.8 Pre-release (pre-reupload or reupload), it will add the map features tag, but set it to 0.

The only ways to avoid this is to skip Beta 1.8 Pre-release, and go straight to Beta 1.8 Pre-release 2 ;) or later. This will add the map features tag, though will set it to 1. This can be also reset through level.dat regeneration, or via classic level corruption.

This discontinued feature is exclusive with many other normal Minecraft items/mobs, including some other discontinued features. This is due to the unfortunate fact that this prevents structures other than dungeons and desert wells from generating.

Partially Obtainable
