Sims will no longer autonomously play in ponds. There's a version where Sims will go in the pond with naked feet (requires the WellnessGP) and another version where they will autonomously play in ponds but with naked feet only (also requires the WellnessGP).
Normal Stereos and synced Lot Stereos have their own Audio Configuration File but they only added the normal one for the public Stereo Wall Speaker Metal. I checked all Audio Configuration Files in the SP17 Files and i could only find one which has the same samples, so i added this to the StereoWall Channel Metal instead. It looks like this let's all public Metal Wall Stereos play the same sample now.
