Minecraft: Wii U Edition gets small bug fix update

A new Minecraft: Wii U Edition update is out now, though it’s not terribly important. The developers have addressed three small issues within the game.

The full patch notes are as follows:

– Fix for Mob Spawners not spawning anymore, and showing a Pig inside them.
– Fix for previously created signs being censored for players with restrictive Privacy settings.
– Fix for being able to escape the boundaries of the world by exiting a Boat at the edge.
