I am running 1.7.10 Direwolf with my own slew of extra mods added and I was doing a update of about all the mods to about the best release I could find for 1.7.10 and after rolling TConstruct to 1.7.10-1.8.8 it would crashed anytime we pressed G and cause this error code.

java.lang.NoSuchFieldError: isKeyBindingPressed

I've already tried getting help from the TConstruct authors but they don't support their older versions and said it was an issue with your mod and I needed to update it. I can only find NEK 1.7.10-3.0.0b45 which is what we already have. Anything else appears to be 1.8 and beyond.
