Seems interesting.
Problems:
- I started unlocking the cart in the forest, only needed 5 more coins, but now I can't putt resources in any cart upgrade. I could still put resources in other upgrades but they would bug out when it got to the cart upgrade. Refreshing fixed the resources needed bug but I still couldn't put any resources in.
- I have no idea what the second villager slot does...
- I sent the resources for Metallurgy (it says that on screen but it might have been the previous upgrade) but now the resources part is empty, the "Send" button is still there, and it's stuck. I can still hire workers and trade.
Refreshing now resulted in a fully bugged game now. 2nd villager in quarry and forest, can't do anything at camp, and I still have my bag. The upgrade bug wasn't fixed either.
