By the way the same bug happened on a pro league match but i didn't remember which one.
Hey mahdiawam900,
Thanks for reaching out to us and bringing this up.
After carefully watching video footage you've provided, I can understand that you've placed Nomad's airjab however when enemy was passing by, it did not knock them as it should've and enemy player just walked past it.
Would you be able to advise if this is something that always happens or are there any particular circumstances or reproduction steps that causes this to happen?
Any feedback or additional information about this is much appreciated.
