[2023] Deadlock glitch deals 50000 damage to wall

I use came off of a spike rush game on fracture as deadlock and encountered a weird glitch about her signature ability.
I was at tower A site, my harbour was on site and an enemy raze was down long so I threw my wall into main, it looked like it sprouted up but it disappeared as soon as I looked away, at the same time my harbour threw a cove nearby it.
Later that round I died and it said that the wall blocked 49996 damage (might have been 500k I can't remember)

My only guess is that the wall sprouted but during the animation was pushed out of bounds by the cove, which is what caused it to disappear on my screen.
Has anyone got an explanation for this glitch or has encountered it themselves?
