FYI:
The showertub updated by HL, has lost its shower parts. Sims can still shower, and the shadow is there, but the mesh part is AWOL.
I had a vague memory that there was a known conflict or something that caused it, but I checked it in my test game, same same. There's nothing that should be affecting it that I can see.
I found another version where DiamondEyes had fixed the animations too. That showertub has all its bits, so something is amiss with this one specifically.
Not a big issue, as the invisible shower does work. It just looks weird.
