I have managed to unlock the opened up tents, they appear in the community lot build mode, under community objects all. 

You can find them at prettysims.com

If anyone uses Delphy's face slider hack or the Console debug enabler, they definitely are not compatible with the new patch, crashes out on the loading screen just after the intro video.  Delphy has confirmed facial hack will conflict.  One strange thing I have on my system, (also reported by a few others at MTS), the EA launcher now refuses to install Sims downloaded packages, unless you remove the packages folder from program files/electronics Arts/sims3/mods, easy enough to do with a cut and paste to your desktop, install your downloads via the launcher , then cut and paste the package folder back.  But it is annoying.  I have tried downloads of lots, clothing and shoes, same problem on all, not figured out the why yet, could be a funny pattern within the download, who knows.
