Bard Bug

I am still attempting to recreate this, as I have only had this happen a single time as of this writing, and have not been in a similar situation since.

I was playing Caitlyn vs an enemy team Bard. I was attempting to finish off the enemy Bard and the enemy adc in the tri-bush (red side bot lane), when he cast Tempered Fate on all of us.

After Tempered Fate ended, I auto-attacked both of them 2-3 times, cast Piltover Peacemaker and my net - all of which did zero damage to them, and I died shortly after. At this point in the game I was fed and had a decent amount of items, so my auto attacks alone should have finished at least one of them off.

I am hoping to recreate this or at least find others who have experienced this.
