I'm playing with r2366 which is the last nightly at the old download location. Adjacentstations is of course set to on in my cfg file.
If I start a new game or load a saved game then I can ctrl-build rail stations (distant joining and adjacent building works as intended) as long as I don't touch anything in the railway station building options. This means that I can ctrl-build only 1x1 default stations. As soon as I switch to a newgrf station tile or even change the length or number of tracks on the default station in the build menu the adjacentstations feature gets broken and I can't ctrl-build rail stations any more (not even 1x1 default ones). After this ctrl-build behaves exactly like simple building. On the other hand ctrl-building works correctly for road stations, docks and airports even after this bug occurs. The bug is present even with zero newgrfs loaded. Changing the length or number of tracks on the default station breaks the feature in that case, too.
Wondering which revision introduced this bug. Must have been a relatively recent one as this is a quite old feature (added around ~r1300) and must have worked correctly for quite some time.
