Features don't work since installing Glyphs 1.4.4

I opened up some old fonts, hit compile, as well as the reload icon in the features section…still nothing. Opentype features aren’t displaying as I type. I’ve tried different combinations on the lower left, to activate some, and not others. No luck. The bottom left features preview has no effect at all on the text.

Can you send me the .glyphs file?
And a screenshot of the problem?
