Era: Medieval Age – Collector Set 3

From BoardGameGeek:

The Era Collector Set #3 provides players with two new buildings - giving players all new strategies to explore! With 4 Schools and 3 Weigh Houses, no game of Era: Medieval Age will ever be the same as any other. School: Provides 1 additional culture during the Collect step each round.If within a walled area, provides 2 additional culture during the Collect step of each round instead. Weigh House: Provides 1 additional trade good during the Collect step each round. If within a walled area, provides 2 additional trade goods during the Collect step each round instead. New Disaster: The Migration disaster occurs in addition to the Brigands disaster. Resolve Brigands first, then resolve Migration (player by player). If you have the most culture (at least 1), reduce your disaster points by 2. If tied for the most culture (at least 1), reduce your disaster points by 1 instead
