Hi, looks like you have a mob spawner causing an issue, not sure if this is an F/A related crash.

The easiest solution would be:

- Make a back up of your world in case something goes wrong

- Open the forge.cfg file in your \config folder

- Search for the line "B:removeErroringTileEntities=false"

- Change it to true so it says  " B:removeErroringTileEntities=true " 

''' Start up your world again and see if it still crashes. Optionally you can set that back to false. What this does is instead of crashing the game, Forge will just automatically delete the offending block. '''
