Can you send the whole log please? What version are you on? The issue you referenced has already been resolved.

• Biomes o plenty
• endergetics
• better End Forge

Hello, i investigated my modlist and i found out your mod was not the cause of my error.
It was infernal expansion : infernalstudios/Infernal-Expansion#270

Have a great day !
