Ambrosia's Lighting System

I had the time to check on the lighting system today...


What I found was disturbing. It's not operating correctly. I was working the last time I tested it, now the glowstone acts just like glass. No redstone signal passes through the glowstone when the repeated is active. I don't know if this is a change that came in 1.0 or a glitch. Whatever the case, if this doesn't get fixed, the map will be delayed.


EDIT:

Solved. Now, I need to replace all of the lights with this...
-_-
