Hi, I installed the modpack on my server and on my client but I noticed that some of the machines from rocketry can't be crafted and some ores from lib vulpes don't have use. Is it a client bug or a server one?

neither, its intentional

neither, its intentional

then why add it to the game?

Essentially, mod authors sometimes make OP items, with unbalanced recipes. Modpack authors, among other things, alter the recipes to create a more rewarding, progressive experience. And oftentimes they'll remove stuffs that's simply too OP, or doesn't fit in with the rest of the mods. Also Advanced Rocketry being in alpha I believe, has a lot of bugged items, hence justifying their removal. Hope that clarifies stuff for y'a
