this is most probably it.
I remember looking at an uploaded replay at slow speed where it seemed like VP caught illidan. And it was a hitbox issue.
Was doubly stupid because I told Blizz[censored] that Huginncord seemed to have figured it out… Only to be told that blizz[censored] was Huginncord. That got me to chuckle a bit.
said bug report:
that being said, feel free to send your replay to HeroesBugAttachments@blizzard.com and they’ll be able to check to make sure everything is working as intended!
