So I converted 2 worlds that I often used, one of them being the world that I've been working on for the past several month. So I converted them, everything was working perfect I closed the game and no problem. I woke up this morning open minecraft, both world aren't on the list anymore, what?! I can't believe this is happening, SEVERAL hours lost? No there MOST be a way to find then back right? No mob no texture pack or anything installed but Minutor.
