When building a tile to replace another, the tile gets built, then demolished.

I noticed for a few builds now that when you build a tile to replace an existing tile (for example an airflow tile with a normal tile or with an insulated tile), then after the new tile has been constructed in place the tile gets deconstructed again by a dupe. I haven't witnessed it on screen yet, but it is a reoccurring pattern that placed tiles disappear and I have to set the task again to build it.

Deconstruction is not shown as an assigned task to the tile.
