I'm just speculating, of course I do not know exactly how often a Neotropical wall happens. But I saw one in April and haven't seen any other since then. Other wall types seem to occur more often (I watch the AP just for fun ), I've seen several Bleeding Moon, Dorsal and Canopy walls.
Re new release: no message in the News forum, so I won't hold my breath...
LadyNova, that is really nasty, I'm so sorry! Who would want to do such a thing? Did you annoy someone in a discussion? (Of course that wouldn't justify such a reaction, I'm just looking for a possible explanation.) I'd support a feature to hide growing dragons on your scroll and not just adult ones (why would anyone want to do that anyway? I don't see the point.).
