Help/Tips Reproducing Azir Bug

Essentially, my friends and I found a bug where I (Azir) ulted the enemy Brand against the wall inside our base and it launched him into our Nexus (think new Poppy's ult backwards), but we're having trouble reproducing the interaction. So I'm looking for tips or possible help reproducing it (ex. a place in the game files where I can see the unit location when an a key was input)

Summary of interaction: Enemy Brand standing inside ally base (blue side), along the bottom wall, near inhibitor. Azir ults Brand towards the wall. Brand flies up (along the Z axis) higher than normal and flies towards base (looks similar to poppy ult). Brand dies from fountain dmg.

Exact location of Azir and Brand unknown. Exact angle of Azir ult unknown.

It was really funny when we did in game though; obviously broken if able to someone could do it willingly. It's just a shame no one on either team was recording/streaming this particular game to upload for Riot repro.
