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


  • Due to the addition of tools to mine certain blocktypes 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 two 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.
