I take it you mean tribute from wars? If that is the case I have logged this as a bug and we'll see what happens.
As for the tributary relationship itself. It gives an automatic improvement in monthly relations making alliances easier. We did not feel it was exactly the same as the vassal relationship in EU, which ment that de jure both sides were one country even if the vassal itself was de facto independent. Here you have an independent state who is buying off another one.
