Weil ich mir selbst nicht so sicher war, ha ich nochmal nachgeschaut (S. 9, Building Actions, Heŕvorhebung von mir):
ZitatIf there are any buildings in the inhabited area attached to the Forest region at the moment in which you place the die, you may perform the action shown on one of those buildings. Unlike Forest Actions, you may use a Building's Action regardless of the value of other dice in that Forest region. But, your die must still be higher than or equal to the value shown on the Building you want to use.
