Miko Bug In Echilon

Was playing with Miko in Echilon on PC, Was on the middle bridge, and threw my ultimate on our feets.
But nothing…
then wonder… what if it went bellow, jump down the bridge, and there it was, the fungus went through the bridge to the lower end.
Dont thinking on reporting it because Im not sure how I did it, and couldnt record it last time.

Some body have reported this before?
