Jayce Hypercharge (Ranged w) Animation Bug [GAMEPLAY]

To give backstory, just played a game as Orianna mid vs a Jayce. In a few jungle skirmishes at approximately 20-25 minutes, I was noticing that I was literally being 2 shot by his auto and his q. Upon looking at the deathrecap, I noticed that his one hypercharge auto had done 1.5k damage to me. Now, this damage may not seem ridiculous if he had a full build, but it being around 25 minutes, the enemy Jayce had his tier 2 boots, a ghostblade, an essence reaver, and a muramana (muramana damage was separate from the hypercharge information). I calculated that each auto of his hypercharge (I used his stats as if he were level 15 with full ad quints and a rank 5 w along with the items that I listed above) should've only been doing around 700 damage per crit. My first item, by the way, was an Hourglass. I did not factor in the damage mitigation of armor, so Jayce should've only been able to crit for around 700 damage per Hypercharge auto given that his target had 0 armor, which I clearly did not.

During the game, I had suspicions that all of the Hypercharge autos were being consolidated into the very first auto, because the damage wouldn't have been outlandish if it had been done in the three attack animations, as intended.

After the game, I immediately went into a custom game and replicated the bug within minutes. If you use Jayce's Shock Blast immediately at the same time or slightly after the first attack animation of Jayce's Hypercharge, all of the Hypercharge autos will either be consolidated into the first animation, or the third attack will be consolidated into the second animation. Regardless, this effectively makes his Hypercharge cast in 1/3 or 2/3 of its intended cast time and, as you can imagine, the burst damage from this combination can literally one shot anyone that hasn't stacked armor to an insane degree.

As far as how frequently I was able to replicate this bug, I only spent about 5 minutes in a custom game and tried it for 6 or 7 rotations of spells. I was able to replicate it 3 times in total. I would love to submit video evidence as proof, but I lack the software required to capture gameplay footage and I don't feel as though screenshots have the ability to properly depict the potency of this bug.

Edit: Added more detail about the time and item threshold of the Jayce to give more insight into the gross damage output
