Pyke Ult/Lifeline/GA Bug [Gameplay]

There's a lot going on here, so it's not super clear what's causing the issue. After dying with GA on during a Pyke ult, I was transported back the lifeline I had placed earlier, but it seems like I was immediately transported back to the location of my ult despite not having executed anybody with it. So I think there's either a weird interaction between GA and Pyke Ult or between Lifeline and GA, Lifeline and Pyke Ult, or all 3. Very odd behavior.
