Crash at placing train ghosts

[Pfeffi]

Greetings,

my game crashes guaranteed when I try to place ghost trains from a blueprint over partial ghost rail tracks. The important detail is, that the ghost trains will be placed on an area, that contains already placed rail tracks and also ghost tracks.
Oh the train blueprint also contained rail tracks in the print. I think, this is also important, as I alsways use them for easier placement.

As far as my testing goes, I can reproduce it consistently.
