What happened?

So I was just placing some Mekanism universal cables to power some simulation chambers and loot fabricators and the game just suddenly crashes out of nowhere, I suspect Mekanism covers although i never placed any.

Had a look at the logs but I don't know what Cannot invoke "it.unimi.dsi.fastutil.objects.ObjectArrayList.get(int)" because "this.wrapped" is null means.
