I was doing the exploring delta volanis mission and the system on the left requires me to beam down for medical supplies. But during the loading screen I get a fatal crash and error message saying something about an unexpected code. Tried to log back in and its doing the same error during loading.
This seems to happen a lot in Delta Volaris; happened during Closed Beta, too.
As for the crash on login, it's because your toon is still down on the ground, where the map isn't processing right. If you wait about 5-10 minutes before logging back in, you'll be back out in your ship again. Or you could make a second character and play with it while you wait.
I'm guessing this is one of many bugs the devs are still trying to squash. They might need armored boots. :3
