TamlWrite not saving Controllers properly?

Hey all, it's been a while but I'm back with a new bug that I need some input on. Basically, I've discovered a problem where the TamlWrite() function does not include all the information necessary for certain controllers to allow them to be loaded back properly at a later point. I'll stick to the buoyancy controller today, and if we get it fixed and it doesn't help with the other thing I spotted I'll post that later.

First, replace your Sandbox's BuoyancyControllerToy with this:
http://pastebin.com/t6Xru5iK

While the toy is loaded if you press F2 on your keyboard it will save an xml-based Taml file of the current scene to your Documents folder. Pressing F4 should load the toy back to the moment you previously saved the scene. If this does not work, I believe practicing01 will post how he replicated the error just after this post.

Here's the bug: When you press F4, it will attempt to load the scene but crash when it reaches the Buoyancy Controllers' FluidArea fields. This is because only the first two numbers (out of the four required for the X Y X Y coordinates system) are saved to the taml file.

Here is an example of how the taml is saved versus the original script creating the controller:
Taml File excerpt:

<BuoyancyController
            TamlId="1"
            FluidArea="-50 20"
            FluidDensity="2.5"
            FlowVelocity="13 0"
            LinearDrag="3"
            AngularDrag="3"
            FluidGravity="0 -29.8"
            UseShapeDensity="0" />

Original code:

%this.createFluid( "-50 20 30 30", "1 0", Navy );

As I said before, I believe I have found another place where the controller information was not saving correctly (that one was on a PointForceController), but I'll wait and see if a fix for this fixes the other thing.
