After i updated from buildcraft 6.2.6 to 6.3.1 my world wont load (new or old). The game starts but when i try to load a world or make a new one (SP) i get sent to the MP window.

So i dont have a error log to submit but i can zip/rar my mods and settings and put them on dropbox if that would help.
Using forge 10.13.2.1277

What mods are you using?

Shutting down internal server? Is it that window?

i'm using about 220 mods so listing all off them is abit mutch. But i'm mostly using magic mods with there addons (Thaumcraft, withcery, blood magic Ars Magica 2) then i'm also using most of reika's mods (cromaticraft, rotarycraft). Here is a link to a rar with all mods https://www.dropbox.com/s/tobe7hxwivsxjds/mods.rar?dl=0

You can go to your modpack directory and get crash log there.
Probably - Roaming/nameOfYourModpack/logs/ and find log with the right date and time

http://pastebin.com/T4z2NSrr
this is the log file inside the .gz file in the logs folder.
if you want i can also give you the
fml-client-1.log
fml-client-2.log
fml-client-3.log
fml-client-latest.log
fml-junk-earlystartup.log
latest.log

Are you using optifine?

no i'm using fastcraft 1.16

no this is renderring issue... it's about missing textures... maybe texturepack or corrupted mod file

well i dont use a texturepack and its only when i change to buildcraft 6.3.1 it happens
