I've encountered dozens of missed links in my games. But much more seriously, the map has two "Fairfax" territories on top of each other and crashes whenever you try to take the smaller one. You can select the territory, but it has no information. It not only crashes the map, it crashes the browser.
The larger one is Fairfax County and the smaller one is the City of Fairfax. I'm in a few games on this map, but I haven't had the chance to take the City of Fairfax, so I haven't encountered the crash problem.
Taking Fairfax (either of them) doesn't cause a crash. it must've been something else that was causing a crash on that move when I was trying it. I will suggest that you not even bother attempting to click on the cities on the big map to execute attacks. Just select the one you want to attack from hit "more info" then select the adjacent territory you want to attack and enter the number of units. Frankly this is the only way to do if you are rapidly expanding and want to hit those 4 cities within territories around or inside Farifax. Cause once you confirm an attack the arrow stays on the map, they obscure the other spots you want to attack and it becomes impossible to attack alll of them in one turn simply by clicking on the big map.
