I play rotationally and now have 5 different sims that randomly get the "creation itch" energized moodlet without having the creation itch ailment. There is no option to cure, all I can do is cheat the moodlet away but every 8-12 sim hours it returns and I cannot stop it. It just appears again over and over and over and has for over a full sim week per sim. Its preventing these sims from sleeping and not helpful in the slightest.
Ive removed mods, repaired the game, saved and gone back to manage worlds, saved and gone back to menu, saved and quit and restarted entirely and still nothing no option to cure ailment and the moodlet keeps appearing.
