I was messing around with a friend, practicing CSing, and I decided for random reasons to do 180 drifts in my fountain, and I noticed an interesting bug. If I cast my ult in this way while drifting in the fountain, not all of the soldiers would spawn. I could get this to work pretty regularly, though the number of soldiers missing from the wall varied.

In this picture I had a level 2 ult, which means the wall should have 5 soldiers. It only has 3.

I surmise this has to do with Azir trying to travel outside the boundaries of the map, and when the soldiers for the wall spawn, they spawn in illegal bounds and are deleted from the game.
