Elite ->Normal - Bug?

Yesterday I did quest called Craftsmen Rescue (it's daily quest in capital city - GREEK) and it was soooo easy. I am level 8.
Today (at the same level !)I just wanted to try elite difficulty on this quest but it was unplayable so i switched it back to normal BUT Normal is hardcore now. CPU build towers everywhere on map, his army is much stronger than my and I cant destroy one histower with 100/140 army. Is it normal ? I think its pretty hardcore and somethig gone wrong when I switch to elite and than back to normal.

Sorry for my broken English.

|||Abandon quest, then re-accept. I think you really need siege weapons to do this on elite. By the way, you can bypass the town and sneak in from the back, then you will only have to deal with 2 towers, instead of 4 + a town center.
