Thanks to the detailed Forge crash report there's a way to solve this (and similar errors) without reseting or reverting the whole world but it requires some manual work.

What you need to do is manually remove the offending block/tile entity. Here's a quick guide on how to do it:

  1. Get NBTexplorer or similar program which allows you to view Minecraft region files.
  2. Take a look at the "Block Location" line in the crash report. In your case "Block location: World: (-118,65,104), Chunk: (at 10,4,8 in -8,6; contains blocks -128,0,96 to -113,255,111), Region: (-1,0; contains chunks -32,0 to -1,31, blocks -512,0,0 to -1,255,511)"
  3. Get the region file indicated by the error (bolded). In this case you want the file called r.-1.0.mca
  4. Open the file in NBTexplorer (or your program of choice)
  5. Find the chunk at location indicated by the crash report (underlined). In this case -8,6. You'll have to manually find the index tag where the chunk in question is. Just look inside the "Chunk [nn,mm]" ->"Level" for x and z coordinates
  6. Once you find the chunk, search through its TileEntities list for a TE at the coordinates indicated by the error report (italic) and remove it.
  7. Save and replace the old region with the modified one
Remember to backup before editing!


P.S. Sorry for the late response but I thought I'd share this trick for fixing crashing worlds. This method has saved me many times from reverting to backups or even trashing the whole map. All this is possible thanks to the awesome detail of Forge crash reports. Kudos to Forge team for that!
