I do not even have Eco and after the previous patch (I think it was a few weeks ago?) my sims started showering constantly. I took all my mods out completely, I mean CC and all mods except MCCC. Still had the showering issue. I deleted the tuner config file from MCCC and the problem went away. I set up a new tuner config file and for two weeks everything seemed fine. Now the showering issue is back. If I turn off the autonomy for the "bookshelf" (and I think there is about 5 of them) the showering issue comes back. And not just my active sim but NPC's that come over to visit. If I turn the autonomy on for the bookshelf the showering issue stops. It's got to be some kind of EA bug. From my experience any time there is an inexplicable issue it's usually EA.
