List the steps that occurred before the bug happened:
1. Pick Seraphine ult on Teemo in the Ultimate Spellbook mode
Flash, use Seraphine ultimate
Attempt to auto attack during the Seraphine ult
Expected Result: Auto attack goes off, being able to auto attack for the rest of the game
Actual Result: Unable to auto attack for the rest of the game, even after dying, disconnecting/reconnecting from the game, and dying with guardian angel.
There were a few ults that could break Teemo's auto. All of which should be addressed with today's PBE release.
