API not working

No matter what I do, I cannot get APIs to work. Even if I have the game launched and am currently inputting commands, it just keeps returning "No existing sandbox found.  Preparing sandbox to start on game activity." Things I have tried: Copying the game Starting a new game Installing mod library APIs to ensure its not a problem with my custom API Restarting the sandbox manually Restarting my browser Changing browsers Logging out and logging back in How can I get this feature to just work?

Hi flop! Just double checking: You are installing scripts on the particular Mod page associated with that specific game? I.e. the link at the top of the Mods page where it says "Mods for [your game name]" goes to the game you are currently active in?

Yep, I've been making sure of that

APIs decided randomly to start working today, not sure why.
