The Rift Heralds were literally making the Summoner’s Rift rumble.

One of the minor bugs is a bit specific.

The Triumph bug ends once overheat finishes.

While that bug already gives Rumble players a huge advantage, it doesnt break the game entirely.

However, the second one discovered could be described as quite chaotic.

Players also exploited Rumble by creating an endless number of Rift Heralds.

This of course would cause a huge problem.

Riot also ensured that the mechanized menace will return to the roster after the bug has been fixed.
