Hi Billy...well, a couple things come to mind here. First, you're right up against the 140 plugin limit with 131 active. The game can start to freak out once you pass 125...some people can load more without issue, but it really has to do with the specific combination of mods you're using and how they interact with each other. Personally, I would start deactivating mods in your load order from the bottom up one at a time and loading the game to see if gets fixed...this could be a mod issue, and the only way to know for sure is to check each mod one at a time to find the culprit.
If you can, post your load order with only the active plugins listed in a spoiler tag to save space...your list shows 131 active, and 137 total. Can't pinpoint what mods could conflict with each other without knowing exactly what's "on".
