Hi, Solarius
I think there's a misplacement for Kuwait City:
[66.6, 66.6, -34.31, -34.31, -1, STR_KUWAITCITY] - those coordinates are actually around Ghizil in Afghanistan...
Wikipedia says Kuwait city is around 29.4N 48E, i.e. [48.0, 48.0, -29.4, -29.4, -1, STR_KUWAITCITY]
Also, Fiji's capital [178.5, 178.5, 18.13, 18.13, -1, STR_FIJI] is Suva.
And, finally, please find attached some other cities across the world (I use a slightly modified OXC that appends instead of replace the mission zones)
