Exactly how much boost do you need to clear miasma and build a road in one turn? I always get the 15% virtue and the 10% Recycler quest and I know that's not enough. I am deep in a game now stuck at 2 turns and I am wondering what I missed. I know of two other 10% quests, but I always forget what buildings they are on, and I can't seem to find a decent guide showing buildings and quests together. The game wiki is useless to find this information.
