The way AI is handled will be changed in the future which should eliminate this. Like Socman said, try placing a pump - well. Learning how to play the game is part of the fun. If you messed up, restart and try again. I will explain this issue further though for you and everyone else coming across this. The minute you assign a nugget to a task (builder, engineer, cook, etc) they are placed into logic loops for their specific task. You have a few things that can break these loops. Mating, thirst, and hunger will break the specific task loop. All nugget tasks have many loops to check which is why buildings aren't built right away. If you guys would like to see a god ability to speed buildings up, create a topic in the suggestions forum. Lets make the game enjoyable for everyone.
Also, for those of you who have not played the tutorial (even if you followed us since the beginning, i would suggest you play the tutorial. You now have access to 4x speed)
