Base production abilities, which increase production for a short time, last 24 hours. During these 24 hours, it is impossible for you to use the ability again. Would it be possible to shorten how long the ability lasts to say, 20 hours?

I was thinking about this myself....

Dan.... since the production buff only needs to be up before the base production timer hits 0, how about removing the buff (regardless of any extra time left on it) immediately after the base production timer hits 0 and calculates the new day's totals... that way at any point throughout the day the buff can be reapplied
