Why is the romance option gone?
After I installed a mod and cc the romance option has not been there. I've tried disabling mods and reinstalling, but it doesn't seem to be working. The cache doesn't seem to be the problem either.
Move your Mods folder to the Desktop and delete localthumbcache.package. Then test the game in a new save.
If it works now check for updates to your Mods and CC. Add it back a little at a time while testing until you have found all that are broken.
