One Second Later...
Simply put? Removing a waypoint that's sitting on a pillar removes the pillar too, even if the pillar modification tool won't let you. That'll result in a quick railway collapse. However... it doesn't happen every time.
Reproduction:
- Build an elevated track with a waypoint positioned directly on top of a pillar.
The waypoint must be added while the track is a ghost. The copy tool will not work. - Using the Modify Waypoints tool, remove the waypoint.
- Watch the pillar be removed as well. Works on both ghosts and completed tracks.
If the waypoint was added to pre-built (non-ghost) tracks, the pillar will show deconstruction boxes with the waypoint, but will not disappear when the waypoint does. - BONUS: Cancel the removal of the waypoint on completed tracks before it actually disappears!
This reverts the constructed waypoint to a construction ghost with no materials- a resource deletion glitch. I know, I should be putting this on a separate thread, but...
