Tomoyo, yes. I had preserve random seed on. That will force me not to reload. ^_^ When I first play it, I can't resist not to save/load if a supper-spearman standing and laughing at me. :-@ Aggie, Thanks. Your post is interesting. I should say I won't do a test like that. I am too lazy. ^_^ For my experence, if the Preserve Random Seed is on, player must do something like investigate cities or wait a long time after steal 4 techs successfully.
