I was curious to see if there were any updates at the time. I didn't buy the script though. Now just a few suggestions that I've noticed:
Make the script random when combining the jug and grape, not the first grape and first wine in inventory. Also instead of using the mouse all the time, try and make it random to where it goes between space bar and clicking it. I think this would make the bot very undetectable in my opinion. But once again I'm not sure how heavily botted wines are.
