Hello, I made a personal modpack, and when I added Spartan weaponry, the game crashed. I tried older versions, but they kept crashing too.

The game crashed: there was a severe problem during mod loading that has caused the game to fail
Error: net.minecraftforge.fml.common.LoaderException: java.lang.NoClassDefFoundError: com/oblivioussp/spartanweaponry/item/ItemQuiverArrow

Here is the log for the latest attempt at opening the game
