TJSGameSettings getStore not saving properly?

I have a bizzare interaction right now with TJSGameSettings.getStore / getWritableStore.

It gets updated, I even see in the console through

game.settings.get

game.settings.get

that the setting has been "updated"
Then I refresh and the changes made disappear. What gives?
