I was playing for hours after installing the current mod list. I've only done some updating since and it was, to my knowledge, proper. However lately I can no longer play. My game freezes every 15 or so minutes. It's seemingly random. No one in-game action or another seems to trigger it. It has also crashed once while clicking on 'Save' in the main menu. I have all Auto-saving features off and I do not use Quicksave. Below is my current load order/active mod list. Any tips to get me in the right direction for solving my problem are much appreciated. I used to mod Skyrim but it has been months and I'm a bit rusty.
