I've got the mod downloaded, but whenever I start up the game it comes up with an error stating:
"Mod scguns requires framework 0.6.16 or above".
It doesn't show any additional mods on the page aside from curios which I've got installed already, and I don't need the tweaker. Is there a specific name I can look up to find whatever framework mod I'm missing?

Mod called "Framework" by MrCrayfish. You can download it from Curse
