I'm drawing out a lighting grid that involves a lot of pipe breaks (girders, HVAC, etc. interrupt the pipes).
When drawing my horizontal pipes, I've had zero issues. Draw all the segments, select all of them, convert to hanging position.
Now I'm working on the vertical pipes, and my first pipe has four segments. All four are lighting pipe objects, all at the same Z height, all in the same layer/class. When I select them and convert them to a hanging position, the 2nd segment disappears from the drawing. I've rebooted the program and it's still happening. No idea what's happening or how to fix this.
