As Thaumic Tinkerer Unofficial supersedes Ichorium Kit, it would be nice if world compatibility was present when upgrading from using Ichorium Kit to Thaumic Tinkerer Unofficial.
Currently a world switching from Ichorium Kit to Thaumic Tinkerer Unofficial will have all Ichorium Kit items/blocks delete, rather than change to Thaumic Tinkerer Unofficial.

If this is too difficult of a feature to implement, then feel free to ignore the suggestion.
