I was using my Applied Energistics 2 Crafting Terminal when suddenly I couldn't open it anymore, everytime I tried it would cause the following Exception:
universal_tweaks_crash.txt
I tried restarting the world (Single Player!) multiple times and came to the conclusion that the Crafting Cache was the issue. After restarting the game, it was working again.

Thanks for reporting, got some questions concerning this:

• So did you keep the tweak enabled and it works again after a game restart?
• Can you remember the last thing you have crafted before it started crashing?
• Which modpack are you playing?

sorry for not replying...

• Yes, I didn't change anything about the mods or config, it seemed to be a one-time problem
• I do not remember the last thing I crafted, but I believe the crash was caused by inserting items into the crafting grid using JEI
• The modpack was Divine Journey 2 (There is a Discord server and I believe that other people have had this issue too, so maybe that might help)

Thanks for the insight, let me know if this should happen again!
