The De-Stressing Concoction is triggered by the Self-Sufficiency NAP. It should only be NPCs doing it (which I suppose would include the Flower Bunny, lol). Unfortunately, there's a bug where played Sims can pick up autonomous behaviours intended only for NPCs. It happens when a Sim is on a lot as an NPC (either visiting the active family, or just walking by, or being visited by the active family), and the player switches households. The NPC behaviours aren't cleared as they should be when the Sim leaves the lot normally, so they stick around (more or less) forever.
There are three ways that I know of to fix it:
- Mods: @simvasion has a couple of mods to fix NAP-related problems. Google "Simvasion mods"
- Using cheats:
- Play a different family
- Invite the affect Sim(s) over
- Ctrl-Shift-C and type "testingcheats enable"
- Shift-click the mailbox and select "Instant Enact Neighborhood Action Plan (Cheat)..." - select the NAP they're affected by
- Shift-click the mailbox and select "Instant Repeal Neighborhood Action Plan (Cheat)..." - select the NAP you just enacted
- Ctrl-Shift-C and type "testingcheats disable"
- Continue playing
- Temporarily disable the EP. This is a very destructive method (it removes all items from the pack that you've used in CAS or building, and completely resets Evergreen Harbor). I did this last week, and it worked, but with two other effective workarounds now, I wouldn't recommend it anymore.
Once your Sims are fixed, they can still possibly get "re-infected" any time you switch households (unless you use Simvasion's mods). Keep that in mind when playing with NAPs, especially with NPC voting on.
