Yeah the problem with glass in itself is an issue that for the most part is solvable in certain situations, Game-Guru makes it harder than it should, but some things simply can't be done atm. As soon as other objects that require transparency are introduced into the scene the problem is compounded.
The Water\Glass issue you are encountering is probably the same problem you get with Grass\Decals. Please see this #308
where I reported an issue with decals and grass not working as one would like.
You also get a similar problem when decals - like explosions - happen near water, in that the water will hide any part of the decal that overlaps the water. You simply can't avoid it.
I am guessing that you are encountering a similar 'in-fighting' issue - but maybe Lee will come up with a better answer. Whatever the problem is I doubt it will be sorted anytime soon since it will require a fix in the engine - if indeed it can be fixed at all.
The developer just needs to work around issue like this - game dev always involves compromises, sometimes we just can't do what we would like in a given scene.

I reckon that is about all you can do.
Personally I would set the FPE to the setting that works best when there is no water around the model. And don't advertise it with any screenshots of the shacks in water.
