My Minecraft just crashed with this modpack: http://www.technicpack.net/modpack/details/moonquest-yogscast-inspired.190904
And, as far as I looked into the forge crash report, it said something ForgeEntityRenderer or something like that. I was on a server too.
Forge Team told me to complain to Project Red

I hope you can help me :)

You are using an old version, update to the latest stable build (currently 4.3.2 build 26) and try again

I can't. It's the modpack version :(

Result: Fixed on my Minecraft world! Thx
