Apologies for the inconvenience, but I can't guarantee when it will come back, or if at all. It's caused the database to go down a few times recently and is making things unstable. Because it's a third party app, we have no real control over it. There are only a handful of people still using it, and the priority at the moment has to be keeping the site running smoothly for everyone rather than having it continually going down or running slowly. I may, however, look at building a native Bluemoon app at some point if it's feasible.
