I'm not sure of how the vassalship works out, but I have just persuaded the English into becoming my vassal. Now I agreed to pay tribute (about 7.500) a turn for 3 turns, as I wondered what it was and I wanted to try it out.

Now it seems that nothing has happened except I'm at peace with England - except that my income skyrocketed..???

Now, I'm supposedly paying 7.500 florins a turn, but instead my income is up by maybe 10-12k florins. Do I receive England's income? Is it a bug? What happened?
