Mods need to be kept up to date. I would check each mod for updates. This means visiting the original website you got the mod from and reading the information provided.
It's possible you recently installed a mod and didn't notice it hasn't been updated in a while... Like the university mod you were asking about. You could start there.
If you have too many files, try the 50/50 method. Run your mods in batches until you find the culprit. Remember to clear localthumbcache each time you remove mods.
I have my mods folder organized by creator and category so when I need to find something broken, it only takes a few folders to find the problem. I always check the Broken/Updated Mods & CC thread first. luthienrising is kind enough to post these threads in the Modding & Custom Content discussion forum for each patch.
