well, my character did take part in the Battle of Carteneau .... I guess he was just left there to die but somehow survived the battle field, and lost his memory.

I doubt squareenix will do anything to 'correct' this issue, just have to live with it.
they no longer need to worry about a 'failure' anymore given the game's apparent popularity, and we as its players will get less and less courtesies, just be prepared.
