... but they're not. By which I mean, this is a perfectly reasonable error:
However, if I simply push F to flip the placement...
I have tested, it does not become part of the extant station, but trains will still path over it no problem, and I can indeed use it as a separate station. If it did become a part of the prior station, it would create a convenient way to relocate the main station module without reconfiguring the station, but it doesn't- and given the error, and the behavior in the next image, I get the idea that it's supposed to be unplaceable either way, making this a bug. Now for said next image:
This is drag-placement of the station module. The lower of the two is what happens on the first pass, where it rejects every other one; I made the upper by drag-placing over the lower, where it forgets to reject because every other one already exists. Alternately, a single drag-place will work when connecting to existing trackage- either quick-replace or off the end.
Reproduction steps:
- See above, first two images use the standard placement tool. Also works with copy-paste and blueprints (used in drag-place image), and placement of cargo modules between the station segments.
- It does appear to be necessary for it to be a directional station.
