Route Flags On Main Menu

I have noticed that the German flags for Rapid Transit and Haupstrecke Rhein-Ruhr (Preserved Collection) in the main menu seem to appear as black as I cannot see them. This is a minor bug but I find it very unsatisfying.

 

Ik it’s annoying that they don’t Appear but it depends if dtg can get it to work

 

The preserved collection routes originally did not have flags, but I believe they are now being added when each route receives an update. That's why some preserved collection routes have them and some are still without.
