For reasons to long to explain, I updated again to version 1.4.0-1+0m7. Unsurprisingly, the problem still exists...

The good news is, after messing around again trying to figure out the disappearing feed problem again, i found a workaround!
It is weird, I don't know why it works, and I don't know if it could cause any damages that I am not thinking of...

Simply re-installing the "facebookqml" and "facebook-meego" packages fixes the problem!...for a little while...

Each time i reinstall BOTH packages (I have tried only installing one, but neither by themselves fixed the problem), I get anywhere from 20-36 hours of perfectly normal acting Facebook feed on my event screen.

Though it seems cumbersome and annoying, with a daily rule in ProfileMatic, I re-install both packages from debs every morning before my alarm goes off. We are three days strong, and no Facebook errors or other issues resulting from this.

I used this website to download the debs.
