I have a question about how to combine both expansions in the Treasure Chest forums. I just include it also here because I think much more people may answer in this thread. No answer in 4 days on BGG means something like a disaster
Just by reading the rules, I see potential differences when combining both expansion (great wall and superevent) if the mongols are the seventh tile. As I understand, both items are handled after the normal tile effect, and before the normal scoring, but: which is the order between them? Just to illustrate, suppose the superevent is the Lanternfest, in which players score the persons in their palaces as at the game end. If the wall has not been constructed long enough, the player who contributed less must release a person. If Lanternfest takes place first, this to-be-released person would score. If Great Wall takes place first, it does not score. I think something similar would happen with Buddha, and even could be a difference with Earthquake.
