Users solutions:
- bad pcx image
- problem with a unit on map (bad flc)
- a civ cannot build a unit/building (a civ should at least build a unit)
- probably a bad pcx file for the leaders
- for every small and great wonder, you have to include a wondersplash in the arts wondersplash folder (this can be the same for several wonders) and an individual entry for the wondersplash of the wonder in the pediaicons file (listed after the building entries).
- 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.
- Nathiri points out, usually there is an error message, but text files have also been known to cause mysterious crashes, depending on where the error is in the file.
- check your .ini files to see if there are any that are incomplete, because it crashed my mod without any warnings.
- might just be that the palette for the wonder splash .pcx used isn't indexed properly.

I have to say I had a full working mod before and I was playing it long time and never had any problem with it. There was no unit, flc's missing, no flc or pcx caused any error, no problem with *ini, wondersplashes palettes, etc.
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....
