Okay, first off, got to say thanks to musicfreak for his work, this is a great idea. I wish other modders would take some of these suggestions into account. One of Rhye's main goals of RFC, besides being an Earth Simulator, is to make a fast, quick loading mod. He tries to reduce late-game turnlag by implementing things like plague to lower populations (and therefore, a nation's armies). So by "optimizing" a mod that already had Speed as one of it's primary objectives, you've possibly made it so few other mods are barely worth playing, if you're not patient and don't have a decent PC to play it on.
But anyways, here's what I've discovered. I started my first game with the Optimized files, copied over the Python folder, replacing any files it encountered with identical names. And yes, I did backup the original Python folder, although I did leave that copy (named "Copy Python Copy") in the RFC Assets folder. I decided to run as the Indians in a pacifist strategy in the 3000 BC scenario (not the Unlocked Scenario). Right away, after contacting the Babylonians and the Chinese, I noticed a small issue. The foriegn contact display on the right hand corner of the display (showing you score, war status, etc.) would not display, no matter how many times I pressed the button. But this was only minor, as I typically don't have that table open (it seems to run faster when I don't, no matter the mod). I figured musicfreak might have eliminated that to speed up the game.
But here's my big bug I've come across. Playing as a pacifist, I did little to explore beyond my own borders, more interested in acquiring the largest population in the world. It wasn't until I got Calender that I started to realize something was wrong. Where were the Persians? So, finally, with the date at 700 AD, I decided to take a little peek. I jumped into the World Builder, and behold, what do I see? Only 4 civilizations on the entire map; Egypt, Babylon, China, and me (India).
So my assumption is that the new optimization somehow prevents the game from spawning the new civilizations? I'm going to try 3 things to see if I can discover the problem. 1st, I'm going to restart a game as India, same conditions, and see if the problem happens again. 2nd, I'll run it as someone else. I might try two versions of this step, one with China or Egypt, and another with a later spawning civilization, like Rome or Greece. The last thing I will do, of course, will be to remove the optimized files and try it again, first as the original RFC, and then as RFC Optimized, but only after I manually move every file from the Optimized zip into the Python folder.
I wonder if anyone else has encountered this? I don't think so, as I didn't see any posts about this issue. But because it's compatible with previous saves, I wonder if no one has even tried to start a new game, and are merely playing with games they never finished due to impatience over turnlag.
EDIT: D'oh! Okay, so blizzrd did have this same problem, mentioned in Post 49 and down. I had forgotten about the F2 screen, which shows the stability ratings of your empire. That's what first brought my attention to the fact the scores would not show (since I rarely keep it open), because I wanted to know the risk of my empire collapsing due to overpopulation. I'll also try that after I do a little of the above testing, but this is feels like it might start to get rather messy. What files are we looking to combine? Which should be extracted first? (ie, Wessel V1, do any of your files overwrite musicfreak's?)
