Lunar Rift Turf destroy Dock abnormal

As the video shows, if Rift close to a Dock, Lunar Rift Turf will cover the Dock, when the Rift disappears, the Dock will disappear at the same time, but not in the normal "destroyed" way.

Also, you can notice that when the Dock is covered, the pillars in the water turn into stone like any other turf.
