He did not recall he fixed it. They would've stopped builing usually if they lack enough building capacity, though that's definitely not the cause.
It could be some other issue side-effect. It should be tried at Insecticide to try building with engineers who have baseline building speed, not equal to 2 or more.
Or that may have been his "optimization" of the code, so he messed up with properties of water tiles.
You could build roads in vanilla then switch to Insecticide.
OR! With "stop building" issues Plane Shift can be used to build tile-by-tile, it should work, albeit expensive.
