version .081 64 bit i5 core gforce graphics card 16 gb ram. everytime i go back in to the game everything i have doubles including a new pickaxe every time which you cant sell lol i logged in one day there was an explosion it was all the coal and copper i had stored in boxes doubled and ther was ore everywhere. and there are still issues with the workbench where stuff gets stuck but ive figured out how to get stuff out so no real problem there.
