Pardonnez, mais je vais ecrire en anglais...
Regarding the 4 regions/ports talked by ElNino, I have 2 questions regarding supply:
1. Is the supply level on the DB city tab relavant ? in there it is 5 for Colophon, and zero for the other 3, but on map the supply level is: Colophon: 81, Trapezus: 45, Sinope: 51, Eupatoria 20 (?)
2. Why the number in the map (with supply filter on) for Colophon (30) is different from the tooltip (81), while the others coincide ? (see pic)
