Harbors bug: trade is still 4:1 despite development built
using firefox browser 65.0.1 on ubuntu 16.04 OS. In few single player games now I've had developments on harbors (special 2:1 or general 3:1), the deals are 'displayed' in bank trade correctly, but when I click to offer a resource, I have to sacrifice 4 cards. Re-tried few times, but still had to sacrifice 4 even though a 2:1 or 3:1 was clearly shown.
@lukas_catan I have the same issue. The 3:1 seems to work but 2:1 takes 4 resources to trade.
