title: Get empty lua file when decompiling the luac file
body: <p>I'm trying to decompile some .luac files unzipped from a game.And I tried some tools (unLuac &amp; Luadec) but all of them gave me an empty .lua file with 0kb.</p>
  
  <p>Are these luac files encrypt or I just use the wrong version of tools?
  Can anyone help me to solve this?</p>
