I just downloaded the version 2.11, and I came across a bug. The Europe and Revolution buttons don't seem to work. Even the F2 and F3 functions, respectively, don't work for those.
I have the same issue. I thought it might have been some sort of modification to not let you see what was available in Europe unless you have a ship there, but I sent a ship to Europe, its telling me I have a ship waiting at the docks but it won't let me use the Europe screen!
Has anyone else run into this issue!?
ADDENDUM: This happened playing as New China, which I prefer to play because of their food bonus. I'll try an actual European civ to see if that makes a difference ...
ADDENDUM 2: Playing as New Denmark, I had no problem accessing the Europe screen.
Further, there were no "Europe" sea squares I could see when I was playing New China; this stumped me but when I had my ship try to sail to Europe, it instantly vanished so I thought that might have been some sort of modification. However, the European sea squares do show up playing as New Denmark.
I will try playing several games as Europe and China to see if this "Europe" bug is repeatable.
