[Gameplay] [Invisibility] Maybe an Invisibility reveal bug?

Hello, everyone!

All started getting my ass kicked in some plays. Tried to casually leave the battlefield after an assassination and escape making use of Talon's ultimate's invisibility. Description states that a champion cannot be revealed by any means except turrets, if he's invisible. A few more deaths later, I started getting attacked with basics, AA's... during the invisibility period if the said ultimate... far from any enemy tower. Becoming confused, I wanted to recreate this in custom. Sadly, my friends were unavailable and a bot was all I could afford. QQ

Later edit. Lee Sin's abilities, Caitlyn's traps and so on, give true sight on an enemy. Do you guys intend to keep it this way? Does that not go against the new invisibility thingy? Also, Nidalee's traps and Rengo's ultimate only grant vision, not true sight, so it should not affect stealthed units.

Okay. TL;DR

This was filmed with only the vision of the enemy team. The fact that Talon was fully vizible (even though maybe not untargetable in this case) and not just shimmering proves that something is off.

Thank you for taking the time to read this. I am eager to hear from you guys.

Best regards, Paul
