R77-1 does not hit upon touching the enemy jet

Anyone experienced this bug before? I feel like it happened to me more than once but I never bothered to check the replay until today. Appreciate it if you upvote it.

I had an aim9x pass through a jet and do nothing a couple days ago.

Any idea what could be the reason behind that?
