Shaco bug list.

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 it un-stealth you even if you don't attack.

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

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

if you 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)

I could give you a few others, but that's pretty much the most important bugs he has that i can think of.
