It's a bit more serious than what the last person said. The artist drew baby x adult po**, which obviously got them fired and the story was discontinued . The author has to find a new illustrator that matches the old ones style. That is very difficult considering their financial status (as they get very little money from official websites). There's a high chance that it will never happen and thus the story won't be continued. This is what I found out when the controversy rose, but that was many months ago so some of it may be false.
