Did you ever track down the problem that causes the text to get stuck/stop updating? I'm playing a FTB pack (Lite with your mod from the DW20 pack if that makes sense) and the info panels are mostly unusable for me because of this. I placed a single panel near my reactor panels with a time card just to make sure the info is correct, because all info panels stop working at once. It freezes so often that it started a little joke between my brothers "Oh look time stopped". This also occurs in the default DW20 packs as well. This is SSP.
I can force them to start updating again by running far away [to manually check the reactors] and coming back to base or breaking them and reconfiguring the colors.
If you have fixed it, will the updated version work with 1.4.7 client?
