So I started my mods and this error popped up 

The game crashed whilst initializing game Error: java.lang.NoClassDefFoundError: slimeknights/tconstruct/library/client/MaterialRenderInfo Exit Code: -1

which is weird since I don't have tinkers construct installed or is that something else and how do I fix this.

This is the crash report
