  • The top of the map is no longer fully dark.[verify]


  • Due to the addition of tools to mine certain block types faster, there is now a bug where switching an item while mining causes the game to cycle through the entire terrain.png file and overlay its textures on the mined block. (Starts from the cracked animation textures).[2]
  • Sand and gravel no longer falls when placed above ground, it needs a block update first.[verify]
  • This version had a bug which caused the player to drop 2 items at once when the Q key was pressed. Going back to pick up the items would only give back 1 though. Due to this bug if the player has 2 of a block, then drops the block, it will create an infinite item glitch allowing the player to continue dropping items and be left with 1 item in the inventory each time. Picking up the dropped items would now affect the item count nor stop the glitch.
    • It is unknown when this bug was added or removed.
