I tried to correct the Bulrathi greeting, but the original message keeps popping up instead of the corrected one. Also, depending on the AI leader, certain civs have no message at all instead of the one they're supposed to give...
The civpedia is far from complete, I know. Another thing is the "Mul
itphased Physics" misspelling... (It's on my To Do list, just haven't gotten around to it yet.)
Screens: another thing I haven't looked into yet, I'm afraid.
Final Five: well, the lowest civ is supposed to disappear every 50 turns until 5 remain. This option (from Kael's Assimilation mod) worked fine when merged in w/Patch4e. (Although I haven't checked this option for patches 4f thru 4i... The Barbarian World option was left out in patch4f, because it didn't work). I'll check it and report back on it.
Map size hasn't changed. I usually play(test) on Huge size OK, although I've noticed some lag with Blue Marble mod installed, which didn't appear before; this might be cause for some concern.
Map trading: sometimes you can trade - especially early on, I've noticed, so possibly it's like the larger the map to trade, the less likely the AI is to trade it. (I'd act the same, to be true.)
I will point out that the last version of this mod I used was patch 4b, though I didn't use it much. That one DID work. I'll have to tried the exe thing, though I don't know if it will matter. It starts to load it and goes through all the phython stuff and then fails to continue to the actual game screens.
I understand the problem, but have no experience with the Steam version myself. Another solution
might be to correct the install path the auto-installer gives (type the correct path instead of the given one).
