[Q] CM12, Skype (I think) deleting my phone contacts topic

I thought it would just happen randomly while using my phone, I would go to make a call/check a message and my contacts would be deleted. One by one I could see the names turn to numbers on the call list. Happens a few times a week, have to reimport each time (also imports are glitched, so I get loads of import notifications that don't go away until I restart).

I've now noticed it seems to randomly happen after using Skype. So, is Skype deleting my contacts? Why? How do I fix it (other than removing Skype?).
I've tried googling, but it seems to just be threads asking how to remove skype contacts from android contacts list.
