Game Crashes when I wanna see a recipe.

[Leguan16]

Hey!
Me and my friends created a little mod server (1.7.10 i think recommended forge version) with about 50 mods.

When my friends joined we noticed that their game crashes when they wanna see a recipe. I can see every recipe but they do not.
I gave a friend OP and it worked but on the next day it didn't

there is the crash report. I hope you can help me.
