I think one of my worlds has been corrupted after my computer randomly shut down. I can open any world but that one as it was open during the time of crash. I believe the problem is with chunk loaders but I'm no expert and would like advice.

NullPointerException (the error you're getting) refers to a mod requiring a file that it either cannot find or does not exist. Try redownloading the mod pack (your FTB installation is probably corrupted if there's a NullPointerException, go to Options --> Force Update, then launch) and, if that doesn't work, redownload all the mods from this location on MCForums. All the mods present on that thread are present in FTB, so better to redownload them all and ensure that things work properly.

 

It's interesting that only the one world is broken. Have you ever 1) crafted and placed an Ender Chest on that world, 2) crafted and placed either a Chunk Loader or a Spot Loader or 3) used Wireless Redstone? What makes this world different from other worlds, if anything? These mods are all inter-related as they are made by the same developer and share the same core libraries, so I'm thinking it's a problem with one or more of these.

I've force-updated my modpack but the problem still persists. I did in fact place a chunk loader in the original world but can also place them on others without a problem. It seems my FTB client crashes when I try to open a Descriptive Book used with Mystcraft. I used an age to transfer lava in the troublesome world and just tried to create a new age in a brand new world causing a crash.

 

~Edit~ I entered the new world and tried to make a new age, and it worked. So I'm clueless as to what the problem could be.

 

~Edit 2~ I disabled both Mystcraft and EnderStorage mods and I can now enter my world. Thanks for the help GameStopper
