[GAMEPLAY] Bug with rift scuttler, where the kill is shared between the teams

Not really sure what happened so I went through the replay and made some gifs showing the problem

Overall this isn't a game breaking bug but I imagine in a ranked game teams would not be happy and if this happened in LCS it would be a remake. This is the first time I have ever noticed this happening, but only because I was trying to steal it and was focused on it, I'm not sure if it has ever done this before.

I have the replay downloaded if you want it in full.
