As in the title, my singleplayer world on Tekkit Legends will not open. I have poured many days of effort into the world and would not like to call it a loss. I have tried opening new worlds with Tekkit Legends, and that works fine, but attempting to load up my world only results in showing me a single frame of the world and then closing instantly without any error message. I will attach a crash report so someone can make heads or tails of it, because I cannot. I'd really appreciate any giving me some help here if they can, thanks!
