That Upgraded Trinket bug?

Summoners! Due to a discovered bug with Greater Stealth Totem (Trinket), we've disabled this specific item until the fix is released. Sorry for the inconvenience.

Apparently, the bug is that if you bought this item and sold it a few times, it would crash and delete the game completely, as if it never happened.

That's a fine example of SpaghettiCode™, now available for purchase in your near supermarket. Ask your doctor!
