Bistrasse & Bahnhofstrasse were incorrect on the map, and I’ve now updated them. Bahnhofstrasse is only permitted for buses now, as well as its junction changing away from Landstrasse to Bistrasse. I’ve completed most of the changes except the rejoin to Landstrasse. Official Swiss map shows it correctly.
I cannot rejoin Bistrasse to Landstrasse for some reason … I am level 2 and as far as I can tell, only level 2 permissions are required for this, but when I attempt the rejoin I get an error “Saving Error: You have no permissions to make some of the changes. Suggestion: Check and try again”
All turns are allowed at the Bistrasse / Landstrasse junction.
