Issue description
When placing transports (pipes for example) they do not respect existing pillars and raise "Cannot find valid pillars placement" even if the destination is the very pillar, it would create & use.
Reproduction steps
See the following video. The first attempt is the broken one. While the second attempt is a workaround, I also applied to the water pipes on top of the Ammonia ones.
