1) can you use the Move action card to move squatters away?Why wouldn't that be possible ? We played it like that.
Edit : from the rules : "You may play Move on any tenant, to move them out of any apartment, either one of your apartments or an opponent‘s apartment"
2) can you put musicians into a building which already has musicians, and if so, do they also have to be moved out immediately? The rules dont explicitly state this, but they alude to it, where it says, if you place them in a musicians-free building...Like you said, musicians are making other tenants running away in a musicians-free building; so if there already are musicians in the building no one is forced to leave (thematically it makes sense ... :p)
3) if you have the tavern, do the tenants living in your other buildings that normally pay more than 3 coins rent only pay 3 coins, or do they have to be moved to other (opponents) buildings. I assume the former, but its not 100% clear.The rules clearly state :
"In your buildings without the Tavern, tenants pay a maximum of 3 coins rent. The other tenants immediately move into suitable empty apartments in squatter-free buildings."
So we moved "4+" tenants away when playing the tavern.
