After building an airflow tile over normal base tiles, the "white ghost/blueprint" graphics stayed after building. Originally, the task never completed. however, after canceling the task and re-tasking, the order was complete, however the ghost/blueprint still remained. I made a short highlight cutting out the boring parts. See following link
The problem seemed to have fixed itself after a restart of the save.
Steps to Reproduce
my guess. my not be reproducable. 1. Set deconstruct task on a given tile. 2. Select airflow tile, and create a build task over the tile you set to deconstruct. 3. Observe tile seems to never get built.
