Issues with Google Play Services crashing constantly?

[hurrshire]

I've been having this issue for several weeks now and I think I narrowed it down to Location Services. If I turn off GPS, the crashes stop. As soon as I turn it back on, Google Play Services crashes 10-20/minute. It's at the point where I cannot use GPS at all and forget trying to navigate anywhere.

Running Cyanogen OS 12.1-YOG4PAS2QL on Android version 5.1.1

Any ideas?
I was having a problem with it crashing less frequently and switched off wake permissions a few months ago, this has just started in the last two Cyanogen updates.
