Which treasury goods will be asked to raise province buildings?
Only the eras that are represented
in a guild will determine the costs of province buildings. For example, if a guild has two members, one in Iron Age and one in Colonial Age, then only goods from those two specific ages will ever be asked for. Nevertheless, the distribution takes into account the weighting of represented eras, which means that if a guild has mostly members of Space Age Mars, then it’s most likely to see Space Age Mars goods as costs.
