Issue
Game crash on shooting HV wire with Rainbow cannon from Cyclic
I would suggest removing the Rainbow cannon as it has no direct assistance to the modpack and forced us to revert to a backup as the world was irretrievable and crashed on startup.

Thanks for letting me know :) I've never actually used or seen the Rainbow Cannon, what does it do?

I didn't get to test the item before we server-wide disabled the usage, but a person I play with said it just shoots out a rainbow projectile that does damage. I'm not sure of the logistics of how it works but I would assume its somewhat similar to a mining laser. The ability to destroy blocks though is quite troublesome, and seems to lead to unintentional griefing.
