Really Annoying Kindred Mark Bug [GAMEPLAY]

           Ok, so I was playing a ranked game with a kindred on my team, red side. She marked Rift Herald, but could not take it by the time baron spawned. When Rift Herald was replaced by baron, her mark remained on the herald, so she could not take it, and it was stuck there all game. Please look into this matter, I would appreciate it. Thanks

I am unsure about how kindred's mark works, so here is my best shot:

1. Get A Mark Rift Herald the time Baron spawns.
2. Let Rift Herald disappear when Baron spawns.
3. ???
4. Not Profit
