Mediabay not updating

I’m sure i’ve had this problem before, but cannot for the life of me remember the solution.

Basically I want the mediabay to keep updating automatically, but it just stops. Even when I instruct it to refresh and rescan my samples folder, it just stops. I disabled the option to only scan when media is open , so technically it should do it all the time, but it wont.

Any ideas ? Thanks.
