If you are planning (or using) PI, be warned!!
PI is full with duping glitches! It has the arrow dupe glitch, fast clicking in trade screen dupe glitch, cheat engine dupe glitch (2 times) and much more.
It takes really much afford to get those dupes away and is also really hard.
I advise you to NOT use PI.
If you are going to use PI you have to be a proffesional Java programmer.
Kind regards, Bert
