Shaco's bugs

the clone has no items (70% of the time)

Shaco's boxes don't proc Frost Queen's Claim or Thunderlord's.

when you cancel a basic attack with Shaco while you're stealted and it un-stealth you even if you don't attack.

Frost Queen's Claim's ghosts still chase you while you're invisible, telling the enemies EXACTLY where you are.

box targetting system, if a minion pops it, the box will not attack anything else until the minion is dead (no matter how close an enemy champion is to it). It should attack champions if they're nearby.

Boxes can get destroyed when enemies dash onto them (ex: Riven's Q) and they don't get feared

if your clone is stunned while following an enemy champion (when you command it to attack) He will just stop moving until you give him another command (unless you're dead) and if you die after giving your clone a command to attack, he will not attack, he will simply follow the enemy adc until he gets stunned or dies.
