--- This script will Randomize age, attributes, potential of all players.
--- New attribute will be a value between 21 and 99
--- New potential will be a value between 21 and 99 (but not lower that player ovr)
--- New Age can be lower than current age by 10 years to higher than current age by 10 years
--- It may take a few mins. Cheat Engine will stop responding and it's normal behaviour. Wait until you get 'Done' message.

--- HOW TO USE:
--- https://i.imgur.com/xZMqzTc.gifv
--- 1. Open Cheat table as usuall and enter your career.
--- 2. In Cheat Engine click on "Memory View" button.
--- 3. Press "CTRL + L" to open lua engine
--- 4. Then press "CTRL + O" and open this script
--- 5. Click on 'Execute' button to execute script and wait for 'done' message box.
