Having an issue with a Crash. I upgraded Buildcraft to 6.1.5 and Buildcraft Additions to 1.7.1 too and thought that was the problem, but still getting the same crash on my client and server version.

I am not sure what is causing it. Can someone tell me if this is a known problem and how to solve it?

One of the mods in your modpack is outdated.

Which one?

I wish I knew. Generally, find the one including a "buildcraft" folder in them. DragonAPI is one.
