Wow, a lot of comments! I hope I'll answer all, but feel free to bug me if I leave out something:
@CellKu: I'll check the popups. Mythodological creatures does disappear if anyone first researches Mysticism. Lascaux Paints: hmm, could be that it needs some spicing up. I was afraid the neanderthals would spawn until other barb warriors, I need your report on this. I might need to do some limitation on this, as the barb generation could take it into account... Will check the chopping issue, also I think others reported on the Istar gate, so I need to think of some other effect perhaps.
@xarver, Blue Anteater: I need more reports with info about difficulty level used, etc, so I could see how the AI performs. It could be the AI neglects some techs, might need adjustments. The main goal however was so that the AI reaches Sedentary Lifestyle ASAP, because otherwise it would lag behind.
@Podtxt: I'll check your savegame, but please provide info about your installation settings and game options used.
@civgenius: great initiative, it is exciting to see add-ons for QC!
@Spuma: Thanks. Also, will see about Civ V, for now I want to make this version as good as I can.
@kenhwcan: Can you please be more specific? I need the exact details.
@ungin: hmm, are you sure there are no problems with your OS, or compatibility settings?
@AvatarLDI: Chieftan is a low difficulty level, and I think I tried not to make low levels difficult, so you might not see that much e.g. neanderthals at all
@Sparrowsraven: hmm, I think this is because now there's a new starting era, starting from 100.000 BC and those maps were made for v7.0. They need to get updated.
@geh4th: Relig. texts: hmm, I don't remember changing those, but there could be an error. Treb to bombard: it must be because there's only that much difference in hammers from trebs to bombards. It's vanilla upgrade behavior. Is it unbalanced?
@ono-neko: thanks!
