    Mod grades

    How grades work

    Modpacks get no grade of their own, so we show the grades of its mods. Of its 33 graded mods, 13 are graded A or B, 8 C and 12 D to F. Its newest release is for Minecraft 1.12.2. See the mods

    Mods in this pack35 of 35 checked

    The mods of its newest release (Minecraft 1.12.2 · Forge, 8 Mar 2019). Each check result is for the latest files of that mod, which may not be the version in this pack.

    No harmful code found in the mods we checked

    We checked all 35 mods.

    We have not checked the files in the pack itself yet (settings, scripts).

    Why we show this: a modpack installs the files of its mods, and each mod runs on your computer like any program. Our checks look for known signs of harm. They cannot prove that a file is harmless. In the grade: a modpack has no grade of its own, and each mod's result counts in that mod's grade.

    4 mods send something about you

    We read the code of all 35 of its mods.

    JourneyMapSystem detailsReAuthData we could not identifyFTB Utilities (Forge)Crash reportsVanillaFixData we could not identify

    Why we show this: a modpack runs the code of its mods, and a mod can send things about you over the internet, like your player name or your login. Contacting an address to check for updates or download files sends nothing about you. Not in the grade: sending data can be normal for what a mod does.

    AI

    No sign that AI was used to make its mods

    We found no AI use from before this release (8 Mar 2019) in the 18 mods we checked.

    1 mod shows AI use only from after it, so it does not apply to the versions in this pack.

    17 mods are not checked yet.

    No sign so far that AI was used to make the pack itself

    We looked for AI tools in its texts and found none.

    We have not read its files and images yet.

    Why we show this: some players and servers avoid projects made with AI, and AI in the game can send what you write to an online service. Not in the grade: using AI does not tell whether a project works well or is kept up to date.
