Same here, first quest (Castle lvl 5) accepted but second quest (Castle lvl 6) keeps getting rejected. Seems like it's happening to many of us. Broken system and very poor customer service. This was my first attempted quest of Gamehag. Makes me hesitant to try other quests, many of them take a long time (up to 30 days) and it would suck to invest all that time and not get rewarded.
