Herbs and Veins locations

The spawn of Heartstones & Golden Flowers is definitely not random, they seem to spawn in most area boss maps and some others. I channel surfed in the Snow Witch map and found one of them in almost half of the channels, I doubt that's a coincidence.

They also spawn at Jesters, Drakes, Panda Teddies and other maps in ludi. I doubt that's a coincidence.
