Just bought this - already regretting it. So many simple issues that could be fixed if the owner cared to spend 5 minutes on it. For such an expensive script I'm massively disappointed.
One simple thing that would improve this 100x would be to always tell the butler 20 soft clay, regardless of how much room is in your inventory. All you'd need to do is do that, then make the bot able to handle the dialog of "oh, you don't have enough space, i'll just hold these" then the extra step of talking to him again to claim them and send him back to the bank for 20 more.
For real though, for something so expensive, put a little work into it. You're making money off it, obviously. Will be cancelling my 2nd month assuming nothing has changed then.
