List of errors in the .lang files:
|How To Play Section||Sentence||Correct spelling||en_GB.lang||en_US.lang|
|Engineering > Redstone||needs a power source such as a Lever, Button, or Presure Plate.||Pressure||Line 2225||Line 2235|
|N/A||Recieved invalid form json.||Received||N/A||Line 5487|
in the 'how to play' screen under droppers it says:
When powered by Redstone, Droppers will drop a single random item contained within. Tap the Dropper to open it and then you can load the it with items from your inventory.
what do you mean by "load the it" lol
