Taking Out the Trash still bugged?

[kejrd31]

Anyone who has obtained this, could you share how you went about doing so, please? I started playing this game for the first time after the trophies were quoted "fixed", but this just will not unlock. This map barely ever comes up and when it has I've been very fortunate and been able to bait people to knocking them into it. Probably about 20 KO's in both sides, nothing.

 

I see the trophy is unlocking for people obviously so I just want to know if there's something specific you have to do in order to unlock it, because it appears knocking them into it and getting a confirmed KO once they've fallen through isn't the way to do it...
