OK, I think I have it.
In shader 3, the only channel that shows animation (expand the shader
in the timeline and look to see what's going on) is the glow channel.
Now looking at the glow channel in the shader room shows absolutely
nothing going on, so you'd be very right to be puzzled.
Changing the color to "none" in the glow channel fixes the shader
(which you can see getting brighter and brighter in the shader room,
all by itself) I'm rendering the thing now, and it looks like you've
found an interesting bug. Please do send this off to Matt.

PS: I also changed all the bezier tweeners to linear. Bezier can do
some odd things, and is not always what you want as a default. I'd
suggest changing the bezier tweener default to linear.
OK, 23% into rendering and it's not getting brighter.
One key to this is to see what part of the scene is getting brighter,
the lights would have caused the whole thing to brighten, and the
trees were substantially the same throughout.
