[GAMEPLAY] More Yuumi Bugs, Possibly Related to Morde or the Stealth QOL Change

In the linked video, there are 3 different instances of bugs revolving around Yuumi standing in place, but in reality she's not. The first part I clipped all the way to my friend explaining where Yuumi was pathing and what she did, but clearly that didn't happen on my screen. The second time I ulted her and she stood still, but was actually under tower on the left side, and the third I attempt to ult Vayne, but somehow ulted Yuumi instead?

We believe it may have something to do with the QOL change with invisibility, possibly in particular Vayne, or maybe it's just a bug with Morde/Yuumi interactions in general (although I could find another clip where I'm not even near her and she's still standing in place with my teammates around her)

Pretty game-breaking I'd say.
