Back in 2018, Blizzard revealed something very funny about its iconic mech hero D.Va: Everything about her is a mess under the hood.
Game director Aaron Keller likened the way D.Va is programmed to a "plate of spaghetti," when speaking to Kotaku at the time. When she ditches her mech, she's actually transitioning into a separate hero as far as the game understands it, and this led to lots of weird problems and even weirder bugs.
