Yep, as i mentioned in my original post, the fist time I tried to woohoo by clicking the bed after the patch, the sims no longer went to the bed they had always used before and went to another bed and did the switching thing after woohoo, then woohoo broke, then it came back again, but with the waking and switching sides.
I started playing another household and so far they have had not problem with woohoo, however, i never used clicking on the bed, i only initiated woohoo thru chat now.
I did experience something else wierd with the new household tho. At a party the Spooky Music started playing on the radio. It showed up twice in the sim's action box and I couldnt get rid of it until i reset the sim.
I went back to the household that had the original problem and found that they were not able to woohoo again, whether they initiated the woohoo from the bed or from chat. They were, however, able to woohoo in the observatory, which i think was recently added to the property. I'm pretty sure woohoo worked on the beds before I switched households.
Definitely seems to be object related. Some unexpected ghosts must have slipped into the game and are wreaking havoc on them.
