Easily re-creatable bug involving Zac's E and Warwick's Ult
If Warwick ults Zac while he's midair b/c of his E, Warwick ends up wherever Zac is atm, then Zac continues on his way, but still suppressed. When Zac lands, he knocks up everyone around him like normal, but if Warwick ulted near the end of Zac's trajectory, Zac's landing knocks up Warwick and doesn't cancel his ult. This leaves Warwick to move around + attack while Zac is still suppressed and taking full damage.
