First, I want to thank you for taking the time to compile such a comprehensive list on behalf of the community. Your effort is much appreciated and will be helpful towards making League of Legends a better game for all of us. I will look into some of the gameplay + interface features.

I fixed an issue with invisible skillshots coming out of bushes / fog of war in Patch 1.72.
It's still possible for skillshots to be invisible for high latency connections. If you're playing at <100 ms I would expect it to be rare.
It's still possible for skillshots to be invisible if you fire it a very short distance out of a bush. This could happen at the double bush setup on the left side of Proving Grounds.
Can you provide more details on when you see the invisible spear such as map, location, Nidalee skin, latency?
I realize you can't actually see invisible spears, but you know what I mean.
