As your base increases in size and you get more bots to do the work, this mod can introduce a significant UPS drop. Stuttering every second or so. It seems like 2-3 ms (?, I dunno if it's ms, the thing that you see when you set it up in debug) goes to Concreep.
It's too bad because that later game period is exactly when it's a good idea to have a mod like this, since it can be a bit tedious to manually put up a whole bunch of pavement all over the base.
