Patch broke Sauna Woo Hoo

Another possibility is the energy saver NAP, it could have turned off the heat. Check on your mail box and see if you have any NAPS enacted that could cause this.

I don't have Eco.

I don’t think the patch did that. I’ve had this happen before the patch was done. It doesn’t happen all the time though. They freeze up when they do the kissing interaction after. Maybe they just want to hold on to that moment for eternity? Lol. I just reset them. ?

I've had an intermittent bug where if the sims in question don't "own" the item (bed assigned to a different sim, closets in residential lots with sims that don't live on that lot. Sometimes closets on nightclub lots, etc.) they get stuck when they try to woohoo. I've had it since before the pre-patch for Eco Lifestyle.

I thought there was a bug report on it, but I can't find it at the moment.

Glad it's not just me. Started a new save with an Actress in an extravagant home and first time putting in a sauna. Not nearly as much fun as I thought it would be with this bug.
