City upgrades/metropolis not working
Just wanted to note that in two separate games, the city upgrades were not working on CAK with and/or without Seafarers. Definitely had plenty of commodities but once I had enough to upgrade, that upgrade was no longer available and I couldn't build any metropolises either. Hope it can be fixed soon as we really enjoy playing and this was super frustrating.
There is a workaround when this bug happens... you can also upgrade cities by clicking on the “City Progress Schedule” aka the little card in front of you with all of the board pieces that tracks your progress.
