Rest assured that it is not. I have found a newer build... somewhere.
But that is not your problem. Looks like ThTi was only erroring because Thaumcraft was.
I have been able to run that exact version of Thaumcraft with that exact version of Forge with a lot of the mods you have installed (my modpack )
These are the mods that I don't have and one or more of them are probably conflicting with Thaumcraft 4:
-all of Pam's mods
You should try to run Minecraft without them first to make sure that my "guestimation" is right.
If that works, try re-adding half of those mods, etc. until you find the mod(s) responsible.
Judging by your post-count you should know the gist.
Thanks for helping to narrow it down to a handful of mods instead of my entire modpack. Turns out the naughty child was Pam's Harvest the Nether. Out of all the mods it could have been, I'm lucky it was the one I cared about the least. Thanks again for the help.
