Its impossible to get it multiple times, i did the same thing. I used to do jobs only when i have classes, and its a pain on my gluteous maximus. i still recommend you farming inactives if you have much time than wasting energy and time with unsuccesful hits.
I used to skip to the last job in the group, finish that off get the bonus and clean up the rest. I dont remember my cs when i did it. You can do jobs as many times as you want, the bonus only happens once. Stop asking over and over.
? i finished all jobs 15 months ago, mwahahaha but these guys are right, OP, you only get the 20b once, but you'd make a fair bit from each successful hit too it's a tough job to complete, but keep trying!
thanks a lot brothers and sisters XD . I thought before. 20 billion which is the last job gives 20b everytime you succeed at hitting it XD just like other jobs. Which remains the money we get
