I dont remember .. how long is Lavatory Service announced 
Updates are done depending how important they are and how they affect users.
The most pressing update was, of course, restoring support for multiple-liveries in P3D V5, because that was a feature we lost due to the sim not supporting DX11 anymore so, that feature HAD to get priority, since it's obviously more important to first restore a feature we already had ( users might have bought GSX because of that ), rather than adding a new feature, which clearly nobody would have based its decision to purchase GSX or not.
There's no need to repeat again my last message, which indicates quite clearly:
- What we are working now, in relationship with the whole GSX ( MSFS version )
- What we are working now, in relationship with NEW FREE FEATURES ( walk-in gates without a bus, asked by so many users )
