I have cleared most (all but 1 sector) of the Archipelago and now I'm getting very, very little collectibles.
Since the Halloween event is over, I am only getting single-digit amounts of collectibles, the lowest having been 6 yesterday evening.
As I know other players are getting 20+ collectibles per spawn, I would kindly request this to be fixed - preferrably before Christmas, because we'll end up with exactly the same problem as Halloween when it comes to collectibles inequality.
