Can't finish this quest Says not all fortresses are destroyed and there are no Fortresses left - went over the whole map . I had 5mins to go, Prince - dead, Oasis - 8 from 8 , but even though there are no fortresses left on the whole map - it didn't give the end of the quest - Quite annoying , I waited until I missed the given time looking for any fortress - there were none and the enemy Gyps were wiped out.
Maybe it is an idea to place additional fotresses/buildings then neccessary in the map like in dunum, which has some extra fotresses
