BUG: Marble Key Producing Dragon (MKPD) Habitat
The collection indicator that is supposed to appear above the habitat, when there are Marble Keys to harvest, does not show itself when there are keys to pick up.
When I noticed that I could collect from my Dynamite and Bomb Producing Dragons, I realized that the collection icon had not appeared over the MKPD habitat. Tapping on it, it showed me a floating +1, and checking on my Marble Keys total, shows that it had indeed increased by 1.
Please fix the collection indicator for the MKPD habitat.
