Summary of the problem World Crashes Upon Entering Pack Version 1.6.1 What is the bug? As soon as the world opens, the game crashes and immediately goes back to the launcher. Note that this doesn't occur when in the main menu or creating a new world, only upon entering that world. Mod & Version N/A Link to log file http://pastebin.com/AEEVH1v5 Is it repeatable? Yes, anytime I enter it doesn't work. This glitch is also found in multiple other mod packs, and the only one that there is no glitch is Agrarian Skies 2. Known Fix None.
