A recent change made it so you have to hold the draw to max before it will fire. An internal ticket was re-submitted for it. Added a note to the KI list. Thanks!
#1 Unfortunately, the biome weighting system will not be going live with A19.
#2 If RWG puts any biome that is not forest in the middle, the spawn points are not generated.
#3 Has already been reported and added to the KI list
