How did you get the €-Symbol for the Currency-Unit? I play with the british version, Im seeing it with british street and city names, though I have the dollar symbol, because I use the English Steam Version. Do you have it running in the language of one of the €-Countries?
Well thats weird.. i changed it and it was just working.
Grouping busstops works by clicking on the busstop and select group, then the button becomes blue and pick another busstop to group with. Done :). You can ungroup by clicking on the busstop and click on ungroup.
