[IL] Mermaid Swimming through the ground

Unrelated to the new patch because I've had this happen before. No mods or CC currently in use and updated for latest patch. 

I think this was caused by the sim autonomously going to sit in the boat that was not in use/on land as seen in the first image. After getting off the boat, transformed back into a mermaid and swam around in the sand, went into the house and walked on tail.
