Kalista's ult has a weird interaction with Sona. [GAMEPLAY] Bug.

When Kalista ult's Sona she is sent flying as she should be but is then returned to her original position before Sona can do anything like use her ult. I've only seen this with DJ Sona but I doubt just a skin is effecting it. And I don't know if this still works but If Kalista grabs a Fiddle that is channeling his ult the same thing used to happen, though that may have be fixed as I used to play around with that on Kalista's launch. Anyone else having the same Kalista ult interaction issue?
