Weird moodlet bug

Thanks for the ways to fix it, but i used the last method to delete it and realised why it was happening, they previously had the exact moodlet from eating too many quick meals, but due to me never eating a real meal as they became a vampire and i gave them the weakness related to human food and it making them sick i never thought of eating a real meal, hopefully wont happen again (i dont know if the moodlet is supposed to work like that in the first place but i found a fix so its all good)

Please follow these steps to test  your game on vanilla game with no mods/cc

• Create a backup of your save game
• Move your mods folder to the desktop
• Delete the following files from your user folder.
    - localthumbcache
    - Any lastException Files
    - Any LastCrash files.
• Test your save (you will loose all cc on the save but since you created a backup you can go back to that afterwards) and see if the same error occurs, then report back.

Make sure the moodlet is gone as removing mods won't remove it (remove it with MCCC if necessary before removing mods) and then check if it comes back with no mods/cc.
