Modpack Crashing in Creative

[Cyberdragon]

I made a modpack and am testing it in creative for crashes. It's very unstable and crashes when I try to use the creative menu to spawn in items.

Am I allowed to post a link to the pack? (it's non-profit, I.E. not adfly)

I'm using 1.7.10-Forge10.13.2.1277 and nei version 1.0.3.56. I don't know exactly which code chicken core I have (it's unmarked for some reason, just says 1.7.10), but I know it's at least 1.0.3 because it wouldn't launch with any lower version.
