If you can't take the whole map in 24, and the speed is the same, maybe increase the length of map to 36 or 48 hours max. This map is a great distraction from the other maps that can be very time consuming and intense(which I like most of the time). When they increased the speed last time the servers crashed and froze way too often. Play blitz or other faster map if this doesn't work for you.
Developers: Maybe update or add to the server capacity to prevent lagging and hesitation in other maps may be a solution? (I am not a computer person) :)
