the game looks at the civilopedia file when it announces a completion. That text file can be tricky because you must be very precise about matching names - within the civilopedia file & between it and the other text files. It also will cause problems if things as small as a space or punctuation ( / ; and so on ) are in the wrong place, missing, or duplicated.
I doubt the civilopedia txt file would cause an issue if there is a wrong entry name as the game would function without it if it cant find it. The only thing I could think of that could cause a problem here is if the entry name is correct, but the content of it is causing a crash. I think I have gotten a crash before (if i recall correctly) when looking at a civ's description to see the edits I had made just a couple mins before. The crash seemed to be due to a certain character in it (it was not the civilopedia's image).
What I have done recently, I just removed half of the units and unmarked all remaining units from all civilizations in editor. I added around 10 folders with new units to ART folder and yes I found there few incompatible ini's but those unit s where not added yet in editor or civilopedia or pedia, so this cannot cause any problem. I added around 20 new civilizations and I double checked folders for Advisors, Civilopedia/Races, Flics and Leaderheads. Yes I found there wrong pcx's for one civ, it was visible in the game that something was incorrect. I replaced that and now is fine. I found two more strange errors in game, I have two civs/leaderheads with certain flc's in editor which display in the game complete two different leaderheads??
My 32.pcx had wrong palette and cased crash in first turn now is fixed. I didn't touch any building or wonder splashed, noting was changed, removed or added but the game is still crashing after all changes I've done until today, when I want to build something different than unit, so building, small and big wonder....
Just had a thought, you havent edited the script.txt have you? Not sure if this could be a problem but there are several entries here that show popups ingame when you build something. It may or may not be related though, but it does say that if wrongly edited it can cause civ3 to malfunction. You did say it "crash when building time is finish".
