Thanks! I've been using the special build for a little bit and it's been working like it should. The only glitch I've come across is that sometimes after turning off the alarm, the displayed graph is either blank or wild, but when viewing it through the graphs tab after, the graph looks like it should. Not really a big deal though, it doesn't seem to affect the smart wake-up.
Side note: My phone updated to marshmallow at the same time as I started using the new build, so I don't know if that had any effect or not. I'm just glad it's working again.
