[GAMEPLAY] Jarvan IV ult not dealing damage while alive. (Pretty sure it is rare though)

I had my fair share of annoying bugs with J4 ult over these past 4 years such as if you tried to walk out of his ult hard enough, the system would take pity on you and let you magically walk through it even though it is barely past half of its duration.

This one though ticked me off really badly. Sure, when J4 ults someone but dies mid-air, the terrain may or may not appear but the damage is not dealt. That's fairly known.

But this one, I died after ulting, which would not have happened if the damage was dealt through. Unfortunately I do not know how to reproduce because as you can guess, pretty friggin rare.

Here's what happened though:

  Top lane versus a Rumble. We traded blows, and we ended both being at around 3 bars each. I still had my ult up so I just waited for him to bust his shield off so I can deal as much damage as possible with the Cataclysm. He uses his Shield, and as soon as it died, i use my EQ and ult. So at around 300 he should have dropped to to 100-200. Nop, he stayed at the same amount of hp he had before I ulted him (well excluding the hp gained from base hp regen). I thought it was a visual bug but if that was the case, my next 2 autos should have finished him off, but they simply dropped that 3 bars to a bit less than 2.

I visualized it again and again to remember every detail on how it could have gone wrong, and I still dont understand why the ult didnt do anything. Rumble was not any helpful by answering with a ''Yawn'' either.

I am simply posting this to raise awareness about this issue. First time it ever happened, doubt it will again, but still, it sucks.
