Hi, been fiddling around with two features of the later versions of the mod. I don't know anything about lua so this is actually taking me a few hours. Hopefully someone who needs this will stumble upon it. One is that BuyPlotMode, the mode that turns on when you click the gold coin button so that you can purchase plots, has to be toggled. This is a bit of an issue in multiplayer games, where it's fairly crucial that you make sure you purchase that tile before your opponent. Every click counts, especially if the turn timer is running dangerously low. To fix this issue, you can find "g_BuyPlotMode = false" in CityView.lua and change it to "g_BuyPlotMode = true."
The other issue is instead of providing the cost of things, you are instead provided how much yield you need until you are able to purchase the thing in question. I'm sure this helps a lot of people, but in multiplayer once again it does mean more time is used, and it's such a speedy game that time saved is super important. It requires more mathematical operations, and so in that time, stuff can happen. Like, if you have 200 gold, and need to purchase a 210, 220, and 230 gold thing, then you just need to add 220, 230, and (210-200). That's three operations (two additions, one subtraction) to figure out that you need 460 more gold. However, as the mod works now, you'd see that you have 200 gold, 10 more gold, 20 more gold, and 30 more gold to purchase each of the things. You'd need to add (200+20), (200+30), and 10, which is four operations. Often, because science is going up by a lot and what you need to produce and purchase piles on so quickly, you need to purchase even more than that many things, which makes the gap in how much math needs to be done even greater.
I think it probably helps some people, but the extra mathematical operations is a risky slow down. I looked for a while in the code for how to fix this (I tried CTRL+F'ing "cost" to see if anything seemed relevant, for example) and haven't found it yet. I'll let anyone know if I can find it! I hope the g_BuyPlotMode thing helps.
