Cyanogen OS 12.1 occasionally crashing

So an issue I've had since moving from Oxygen to Cyanogen is that every now and again the system will lock up, and the only way to get it back is to press and hold the power button until it does a forced restart. Today it did it while I was paying for something using Android Pay and it asked me to enter my lock code. II drew my pattern and the system froze.

It's fine this before when using the camera, playing games, etc. It's pretty random.

I've also been having Bluetooth issues, but that's another story.
