From the very start ask your bounty manager if the rules are already firm and final.
But the sad thing is before you are going to ask them, you'll see one rule that allowed them to change any rule as they wish.
No need to even ask because they will be very polite to you at first and during bounty but when bounty ends is when you know the true nature of those behind the bounty management.
it is not the first time that I am convinced that the reward of the Bounty Hunter was equivalent to his work in 2016 and 2017. But then everything just got worse. To date, most Bounty Hunters work virtually for free in the figurative sense of the word.
