Hi there. I have a Minecraft world where I go into outer space using mods, but when I came back on, There were a bunch of chunks that refused to load and looked black (see screenshot). The black holes consumed my space center where I launch my rockets! I tried everything others said. The only one left is MCEdit, but I don't know how to install it and pretty sure it doesn't work on Forge. I am on an Aspire One 722, running Windows 7, and using 1.7.10 Forge. 
  Keep in mind I have these mods installed: 
  Minecraft Coder Pack (MCP) 
  Forge Mod Loader 
  Minecraft Forge 
  Micdoodle8 Core 
  Galacticraft Core 
  Galacticraft Planets 
  Damage Indicators 
  CraftGuide 
  Mo' Villages 
  MrCrayfish's Furniture Mod 
  Wall Painter 
  Still Hungry!
