All script mods downloading with a question mark

Did you unzipped the .package and .ts4script files ? If so, you should stop it. That’s how they’re supposed to be.
Btw, that icon occurs cause you don’t have any software that can open it. And you don’t need to open it because The Sims 4 game will interpret it when launched.
You just have to put the files in your mod folder, turn on the mods settings ingame and relaunch it if you didn’t already did.
