I'm not sure exactly when this was. But, as far as the afk problem. Maybe you could make it so you only get your 'cps', if you click the cookie once every 5 seconds. I don't know how this was implemented if it was a gui or what, but to stop autoclickers, we could make it so you'd have to click the corner of the "chest" every 5m or so to prove you aren't just afking with an auto clicker.
As far as the money problem, getting meebles per cookie is too op. If someone spent like a week on cookie clicker and made 8 trillion cookies a millisecond that'd be op. So, if you were to implement this, you'd have to have milestones.
ie
1 cookie - 1 meeble
10 cookies - 1 meeble
100 cookies - 10 meebles
1,000 cookies - 10 meebles
...
1,000,000 cookies - 1,000 meebles
...
1,000,000,000,000 - 100,000 meebles
or something like that.
All I know for sure is time wasting is all I do
Huge +1 from me
