This is what I found. When SOAP and OIL are combined in radial gravity, the SOAP floats "up", even when the radial gravity means that the SOAP should form a shell around the OIL. Developers: Can you fix this?
I'll get back to this, I don't think I've pushed my changes yet. But the code is done.
I think I held off because I still thought it was weird that oil and soap both fight to float on top of each other. It just looks strange. It does this in vertical gravity too, it's just more noticeable here.
