I found a compatibility issue with tinker's construct, you and mDiyo should work this one out:
Your recipe for "force stick" requires one force log above another. This conflicts with the tinker's construct recipe for oak barricades, requiring one oak log above another. Unfortunately in the code any 3rd-party log (but not vanilla log except oak) can be made into oak barricades, including force logs. This was probably done for compatibility reasons with mods like natura or BoP, but now force sticks are no longer craftable. This is for FTB Unleashed v1.1.3 for MC 1.5.2.
Fixed in Dartcraft 0.1.19.
