Summary0004315: Water causes deletion of ramps and stairs submerged inside (possibly due to grass)
DescriptionWater in version .22 appears to be causing ramps and stairs submerged inside it to be disappearing. But it seems to require grass to be growing on the tiles, or flowing water to do it.

It would actually be kinda feature-y since I would expect water to slowly wear away ramps or fragile structures like stairs, but in the deletion of stairs it ends up blocking flow from going down the missing stairs, and in the case of ramps it leaves downward ramps hanging in the air.
Steps To ReproduceDig into a water source allowing it to fill into a channel made of ramps or stairs. Allow grass to grow in the water. Watch as ramps slowly disappear over a few minutes.
Additional InformationI have not been able to determine exactly weather it's grass or flowing water that makes the stuff vanish. As it requires the water to flow for some time. And when I tested that, I did so by breaching the cavern and draining it there, which introduced underground grass into the water.

According to another person (Ahonek) experiencing a similar issue it seems to happen to muddied tiles as well without water. The information is leading me to belive grass is the culprit, not flows so much. Also it seems to be related to grass dying on the tiles more than just the grass itself.
