Some of us were having this problem a few weeks ago. It's a problem with patching on demand. The map will crash the first time cause there's some problem in downloading it. It'll be find the second time cause It's already downloaded. I know it happens with the defiant bridge/interior as well. It should work every time now. Barring that, if you turn off on-demand patching, it should work every time, though you'll have to spend some time downloading the whole game.
The Foundry Roundtable live Wednesdays at 7:30PM EST/4:30PM PST on twitch.tv/thefoundryroundtable Forum Logic dictates that if the devs don't do what a poster wants, they therefor actively hate what that poster is advocating for.
Forum Logic =/= Real Logic
