I have been making a modpack and recently found out of nowhere that computercraft crashes with ShaRose's ID resolver when starting a world. I had a big talk with ShaRose and he said it was NOT his GUI API or ID resolver, i even tested the betas.
This had also happened with buildcraft but suddenly stopped on the final 1.5.1 forge release and fixed it.

Im not sure whats causing it but here is the report.
