make it so daily missions have a 24hr timer on them. after they go uncompleted for 24hrs, they are replaced by another mission.

in my case, this would be more for the daily missions that require clicking monsters X number of times. these missions are the only time i ever click monsters, the rest of the time i'm instant killing them. also, i typically run the game in the background on my PC while i do something else so i seldom am focused on the game 100%. only then would i spend the time removing crusaders and leaving a clicker in the formation to complete the missions and thats if i have nothing else to do. otherwise these missions just sit in my log for a week or so.

could you add an abandon mission option then?
