Whenever I start crafting something in the assembly table my game crash and when I try opening my save again the game crash with the same crash report.

Here is the crash report: http://pastebin.com/vNKP8LkJ

Buildcraft Version: 6.2.6
Forge Version: 10.13.2.1264

If you need any other information just ask.
Thank you!

DragonAPI bundles an outdated BuildCraft API. Maybe some other mod, too.

Also, that world name...
