Issue description
I've seen two instances of this within five minutes just now, though I'd never encountered it before. After placing a transport (belt or pipe) in planning mode, some portions of the model aren't rendered. In the case of the pipe, the missing portion was the entirety of the pipe and pillars, except the brackets joining the tops of the pillars to the pipe, for about half the length of the pipe (the other half the length was rendered properly). Pausing and unpausing construction (while the game remained paused) didn't affect it. Unfortunately, I didn't get a screenshot of this; the attached save is at that point, but loading it resolved the issue.
The second time, only certain portions of small sections of the U-shaped belt model are missing:
Reproduction steps
Unknown. You can try drawing transports in the attached save, but it doesn't happen all the time. The selected belt segment in the screenshot was drawn from the boiler to the adjoining belt segment, after deleting the end of that other segment to avoid having two adjacent pillars.
