BB has graced me with 71 star coins for all things achieved past level 50 that had xp in them. (all quests done)
Thank you.
I have a bickering nature and paint it as exact, as the various environments I've been through ask me to be exact, every time, or else... consequently I've been looking inside horse's mouth.
I see 10 sc in fairy tale, 76 in workyards as well as 35 in the first workyard. I am pretty sure there were other quests with experience but these examples are enough for me to call the script inept.
Alternatively, front page notification inline with 'we know you will complain so you get some extra loot on explorers for a while' might help shed some light on the approach. Or any notification about latest features of the game.
