Kled Passive Bug

For what ever reason when i was suppose to dismount and become untargetable, I didn't

I immediately hit the ground and was able to move, use abilities and auto attack without delay.

I tried to recreate in a custom game but was unable too, i tried:

• Casting E while being hit
• Being hit with thunderlords while mid E
• Being CC'd while mid E where the cc would also damage me and dismount me

Each time I just became untargetable like intended. Any input or assistance in finding a way to recreate the bug would be appreciated

It didn't happen again during the game, solely because our was DC'd so we remade.
