I noticed a few funny things in the game. Everyone thought that you couldn't get units on Frigates. Well, you can. Load the troops onto a galley and then upgrade the galley ... This is a bug and, as I understand it, it has been fixed in v2.08.
I was also able to perform a mid-ocean troop transfer from one galleon to another. I thought that this had been fixed. Here you see one galleon with no more movement carrying various units. I transferred the explorer from that galleon to the galleon in the upper right - just to see if I could do it. This was the only time I did it as it felt too exploitive. I'm sure this is a bug.
This is something that I like doing with a newly captured city. When the city comes out of revolt, you will lose 1 unit of population via starvation - there is nothing you can do about it. However, you will only lose 1 unit. Then you might lose others as they can only work the close in 8 tiles while you wait for the first cultural expansion. To over come this, I load up the city while it is in revolt with artists, then on the first turn out while one population point starves away, the others add culture and you get the first cultural expansion. Then you start working all the 20 tiles and you can (usually) feed your new city.
Finally, what is up with this gold graph (see below). It really jumps around ...
