Events occur at random as the colony grows and represent the various obstacles and opportunities that stand before colonists in the post-apocalyptic world. You, the leader, decide what action to take, but be advised, not every action has or can have a positive outcome.
A fellow shows up saying one of the colonists are building a rather dangerous house. The builder in question says he knows what he's building. The fellow questioning the builder states it can be improved to not make such a hostile living situation. You can improve the tent with 9 wood or let the builder continue their environmental structure their way.
If improved it states you forced him to do this and it upsets him. But thanks you for the ordeal. A 20 Happiness effect.
