I opened one of my beta worlds, which ran fine until I held the right trigger button to harvest sugar cane quickly. After the first crash I tried again, hitting the button once per stalk, but it still crashed. I loaded again, walked away, and swung at a spider, crashing the game. I loaded one more time, and collected one piece of birchwood before the game crashed. The game appears fine as long as I don't use the trigger button.
