Apparently when the player attempts to place an entity ghost that requires concrete below it on Aquilo, the last type of concrete the player used is used for the new ghost. I'd like access to this value, so that my mod which places ghosts can replicate the vanilla behavior.

Also it doesn't work at all if the player hasn't placed concrete there yet, and there are also some other similar triggers for ice platforms that I haven't nailed down. If those flags were exposed that would also be helpful.
