I have apparently installed a mod that automatically equips/unequips your helmet whenever you enter and leave combat. I don't want that to happen, but I'm not sure what mod is causing it. Does anyone know of a mod in particular that does this? Otherwise, how would I go about pinning down the issue in something like sseedit? Edit: Figured it out. A while ago I had manually installed the skse plugin "dynamic equipment manager". After I found it it was as simple as changing a true to false in the .json file.
