Hi everybody,
I want almost more to share this oddity, then to report a serious bug, since it does not much interfere with the play-experience, but is curious though:
Persists since almost the beginning of the map (https://servers.simutrans.org/list?detail=simutrans-forum.de:13355#simutrans-forum.de:13355), already under Simu r11590.
