I have a 5min countdown clock with a fractal noise layer using the time*200 expression in the evolution. The evolution starts great and simply stops at 2:16... what the heck?

see it here...

a rundown of my setup...

top layor: black solid with feathered mask (vingette)

next layor: text layor with the following expression (thank creative cow)

rate = -1;

clockStart = 300;

function padZero(n){

if (n < 10) return "0" + n else return "" + n

}

clockTime = Math.max(clockStart + rate*(time - inPoint),0);

t = Math.floor(clockTime);

min = Math.floor((t%3600)/60);

sec = Math.floor(t%60);

min + ":" + padZero(sec)

next layor: a png of the shiney logo

next layor: a psd of the textured dark ribbon

next layor: a black solid with the following effects (in order)

-Fractal Noise: this has the evo expression time*200

-Fast Blur: 15

-CC Vector Blur: 20

(this layors tranfer mode is set to Classic Color Dodge)

final layor: psd layor of a colorful graphic I made

thinking it had something to do with the time expression, i manually set a keyframe at the beginning of 0 evolution and at the end of 166x and it still stops at 2:16.

I'm stuck... please any ideas?
