Traveler's Backpack Mod (Entity and Base)

[WWJTLoS]

Hello Everyone,
I'm in need of help because the Traveler's Backpack od for Minecraft was saying that it would work unless I downloaded any version of Cardinal Components Base and Entity. As if they have separate .jar files? Honestly, I am quite confused and would really appreciate the help!

Hello!

They're provided to mod developers as separate modules, however the jars published to Curseforge and Modrinth contain ALL modules so just use those ^^
