From Patch Notes:
Alliance War
General
Fixed any remaining issues where you could mistakenly be teleported back to your starting area as if you had wandered out of bounds in some areas.
Bug still not fixed. Yesterday I was teleported to the starting location, trying to get out of the gate Aldmeri Dominion to collect skyshards. The gates were closed, and I decided to try to get over the rocks (as I understand it there are invisible walls - a relic of the past games), it did not work, tried the other side and suddenly the words "Tamriel", after loading the character has appeared in the starting area fraction. In general, it's time to come up with an alternative way to sneak into enemy territory, close to the starting area, because the real siege of the castle was not only a battering ram to knock doors or destroy the castle walls were saps and attempts to make his way through the sewers, there were attempts to climb over the wall and much more. It is necessary to introduce the possibility to get out of the gate the other, alternative way, of course apart custody there, so that could have gone unnoticed or simply kill (but they have raised the alarm, so the option to kill the poor and is suitable only the strongest players).
