Ever since Jarvis Alpha 1, I can't clean the library.

I installed every version of Jarvis, Alpha 1, 2, 3, 4, Beta 1 and now Beta 2.

When I try to run Clean library it gets to 99% and just hangs there forever.

Hmm, not a expert here, but some small questions:
- you are not using the video/music libary on mysql?
- only video library or music or both?

If so, you can try to make a backup of your existing library and after that, delete it.

So Kodi is forced to create the library again.

Also a Debug Log could help here understanding the problem.
