Simetrical,

I played around with the numbers some more - the maximum number of men in a Roman general's bodyguard is clearly 124 on "huge" and 62 on "large". Specifying a value larger than 31 in export_desc_unit.txt is treated as if it were 31. At the maximum value there is no difference in the size of the bodyguard whether the general is a faction leader or not.

I'd still like to know what the highest safe number is - I think I was seeing crashes when I had the number set to 30 on "huge". My current guess is that the number needs to be small enough so that the faction leader's bodyguard won't exceed 124 naturally. The faction leader's bodyguard reaches about double a regular general's so perhaps the EDU value shouldn't exceed 15?

I don't think this is much help - I assume you're interested in the safe number - but perhaps it's worth knowing anyway.
