I don’t remember messing with any existing creative tabs, only my own and even that was later replaced with a simpler way using getSubItems (iirc it was adding both empty and full battery versions to a tab). There is another thing that the mod did for the april fools update where it would iterate over every registered item, block and ore dict key to generate an ore for, but that is now disabled by default and the function doesn’t even get called.
