I think this should be fixable by passing getVP the owner instead of the state and changing "state.current" to "owner" within the code. So for example, Gardens would have getVP: (owner) -> Math.floor(owner.getDeck().size / 10)

I verified getVP was working incorrectly by making two bots that would only buy 4 Gardens and 4 Estates. One bot would then do nothing, the other would empty the Coppers.

The simulator concluded that the do-nothing bot was the dominant strategy after it won 24 of 31 games--obviously counting the Gardens scores wrong.

After my fix, the Copper bot wins 100% of the time :)
