I seem to have a problem with the route displays on the C2 using night lines. When I set ATRON using 9 for N (i.e. Linie 910), the passenger information system inside the bus and the ATRON screen correctly recognises the N10 line (same for other night routes), sets the displays etc. But the external displays show the line number as 910 (once I managed to even get 909, don't know how did that happen). The destination text is correct, and people will board, the stop annoucements play as expected, so it's fully playable, but the incorrect display bothers my feeling of immersion, so to speak. Is there something I'm missing? I managed to actually get it to display "N10", by overriding through OMSI menu, but I feel like I'm doing something wrong, and it should work automatically.
I apologise if the question has already been asked, I tried to go through the earlier discussion, but my German is very limited and I might have missed it.
