Describe the bug

I've been playing on this mod pack for about 50 hours. This evening, I updated the pack to version 1.7.0. Since the update, Minecraft has been crashing literally every few minutes of gameplay, and sometimes it crashes during startup or even while loading the world. It has probably crashed about 5 times within 1.5-2 hours.

Steps to reproduce

1. You have an existing world on version 1.6.0.
2. You update the pack to version 1.7.0.
3. You experience frequent game crashes.

Expected behaviour

Do not crash

Additional information

Once, the game crashed when I had relic boots equipped, which make you bounce off the ground a few times after jumping (similar to roller skates?). Then I took them off, and after the first jump without them, the game crashed.
Most of the other crashes happened when I was doing things in the ME Crafting Terminal, although I don't think all of them were related to that. I can't point to one specific action that caused it.

Could you try installing a fresh instance of the modpack and see if the issue persists?

I tried the "repair" option to re-download (as I understand it) all the mods and so on. I’m not sure if this is equivalent to deleting everything and downloading it again, but either way, it didn’t help.
I’ll try doing what you suggested this evening and let you know if it helped.
