Today I had an idea for a build I wanted to do, so I started up my minecraft and created a new world. While I was getting the items I needed MC froze and crashed for an unexplainable reason.
I have the latest build of forge plus the following mods.
Smartmoving
NEI
buildcraft all modules
EE
Thaumcraft 2
railcraft
forestry
inv tweakes
Nephs missing blocks.
reis mini map
balkons weapon mod
Ic2
forestry
BC APS advanced power systems.
NEI plugs ins for BC railcraft and forestry.
no void fog.
error report. http://pastebin.com/0MKUGhi2
According to chickenbones it's an error with a mob spawner most likely caused by a mod conflict.
I have no idea what I should do to narrow this down. I really could use some help.
