Repeatable bug, three attempts.
Quest: Gelino - Trail Continues
Action taken: From the World Map loading an army into the quest (map icon titled 'Trail Continues') and after the loading screen the whole game is pitch black except the chat channel and the Attack Protection box. Hitting the escape button does not bring up the game menu. Only way out of game is CTR-ALT-DEL.
Result: Quest broken. Can not continue quests.
EDIT: Just noticed there was a bug report forum inside this forum. Please move thread. Thank you.
