[GAMEPLAY] Yasuo invisible auto attack at start of ult BUG

Description of Bug: On Yasuo, right at the beginning of his ult, the damage notification shows that he does an invisible auto attack.

Video Example

To replicate: Pay close attention/record and slow down the footage

1. Ult as Yasuo

2. Notice the auto attack damage at the start of the ult.

My Note: Yasuo's winrate spiked during this patch. The auto attack of the ult bug was fixed this patch. This new invisble auto attack bug adds a critical amount of damage, especially during assassination attempts on key targets.
