After updating Silent's Gems my pack is now crashing due to a tussle between Ender IO and Silent's Gems reportedly caused by SG asking [net.silentchaos512.gems.item.ItemEnchantmentToken:canApplyEnchantsTogether:201] about the enchantment "Soulbound" from Ender IO.
Which is then throwing
java.lang.NoSuchMethodException: net.minecraft.enchantment.Enchantment.func_191560_c(net.minecraft.enchantment.Enchantment).

• Tested with just Ender IO and Silent's Gems
• Downgrading Silent's Gems to the previous version (2.3.14-182) fixes the crash
• Log with Debug Mode on • https://pastebin.com/bUzbb9Yi
• MC Ver • 1.10.2
• Silent's Gems Ver (that causes crash) • 2.3.15-184
• Silent Lib Ver • 2.1.4-61

Not entirely sure how this wasn't broken before, but I definitely broke it this time. Will fix right away.
(edit) This will need a Silent Lib update, as well.
