I was happy user of this module until I accidentally discovered that this module has 'disappeared'. Disappear and I mean it's not listed in the modules page and my active node ref fields went back to its default widget. The files are still in my modules directory though. I re-downloaded the module and re-uploaded it back a couple of times but it is still not showing up on module's page.

I'm not sure what have caused it and I don't know how long this has been going on. I have installed a number of modules since then so it's really difficult for me to track the culprit down.

Did any of you also experienced this? What could have happened here?
