I've had a 1/5 credo 3/3 quest, where I had to (1) Greet a tree (2) Kill a bat (3) Report to a tree.
I planned to reach 100 marksmanship and then complete the quest to maximize gain.
I've done only the "kill a bat" part of it.
Just an hour ago I had 86 marksman ship, now I've noticed its 106.
What the hell?
