weird invisible collision on top of blue zipline in base

[oraphalmr]

i was testing some movement tech in the "explore nyc" mode and found this weird invisible collision in the hidden king's side, you can easily get here by using majestic leap, or magic carpet by going through the sides, also you can Use abilities from up here, like celeste's Ult you can use from up here, and i guess other people could shoot you too, but i'm not sure if this is in standard matches. Also i don't think this affects any other lanes
