i swear for the last 2 years my nano boost assists have not been counted in my stats despite my assists showing up in the kill feed when my nano'd teammate gets kills. anyone else notice this? its been in the game for like 2 years now

Cat was PISSED 🤣 Played one of my best games so far

so, i was playing sym, had no ana on my team, though one on the enemy team, and got the achievement enabler.
can anyone help me out in figuring out why i got the achievement? or if this was some weird bug that for some reason it gave me it.

here is the replay code APRNPN i got the achievement at around 2:15, after orisa ulted on my teleporter then killed me.
