Modpack Game-Changer

"Reliable" indeed. It works, and it works great. The perfect Block Swap upgrade, enabling significantly more fine-grained customization with an arguably easier syntax (although the ability to directly migrate Block Swap's syntax shows the deep level of care put into this mod). Like other projects of this author's, Reliable Replacer is the best of its kind that I have found so far and showcases an attention to detail which makes it an absolutely necessary tool for any modpack developer's arsenal. About the only criticism I have is that some rules can't be nested in certain ways, which I'm not even sure is an actual complaint considering I'm usually trying to do things I'm not supposed to when making modpacks.
