Hello everyone.
In the latest version of The Powder Toy, I noticed that it was not possible to create the fast-moving pipe that was listed here: https://powdertoy.co.uk/Wiki/W/Using_automatic_PIPE_tracks.html
Instead, the newly created pipe would move at the regular slow speed, while saves which had this older pipe would continue to move fast.
If the ability to create the fast-moving pipe was to return, it would make the game even better.
Edit: The created pipe would also have the elements get stuck on the 3rd last pipe pixel. This should also be repaired.
