Modpack crashes seemingly randomly

[TechnoScrap]

I've created a modpack that works mostly fine (The Lord of the Rings mod that is in the modpack has a custom main menu background but it looks like it is missing some textures) until I load up a world. On one occasion it crashed instantly upon loading the world, and the 2nd and 3rd times it crashed less than a minute after loading up the world. The world I used was a test world I created after successfully installing the pack.
