Greetings.
I have this issue with my game where if I try crafting something new from a mod (happens at random, not 100% of the time), the game crashes.
I am running the current latest version of Forge and I have attached the logs here. Also running the latest version of Java and without Optifine.
This does not happen again if I restart the game and try to craft the same item, but it will crash again with another new item.
This is for Minecraft 1.12.2
