I noticed that the Android MAME 2016 core keeps disappearing from the updater. It used to be on the updater for about a week before it was mysteriously removed.
Recently however, several of the nightly builds of the RetroArch Android app had a strange glitch that caused the online updater to glitch out and not work properly. It had several strange properties and it allowed me to redownload the MAME 2016 core for some reason. The glitch was fixed in the latest build but the core is gone again. It exists as shown here but it keeps disappearing from the buildbot. Can someone please explain this?
