Don't know if it has been mentioned or it's allready fixed in the next patch but i'll write it down.
1.) Regeneration Spell seems to do nothing.
2.) At start i had some creatures running around but that was all. Since then i only had reports of creatures lurking in woods or have been released but i haven't seen none..not even 1 and i'm pretty much late game (10cities+most of the map revealed)
3.) caravans don't seem to transfer food or something..haven't noticed. Send caravans to a city that had no food production and still had none. It's hard to let a ciy grow that has no food production nearby and it seems where nothing can be done about it. How about making a level 1 farm or something that we can build to atleast be able to produce food. Most usefull things start at level 3 but if you can't reach city level 3 it's very much..not nice.
4.) AI is pretty crawling with research. Although i was very long time the weakest, the moment i achieved magical armor and weapons, i was unstoppable. The strongest AI players with 4 times the citys and points where very much inferior with equipment. With those much cities they should have been ages in front of me.
5.) Late Game get's pretty slow..i suppose there needs to be some improvment there. I can understand that such games tend to slow down in Late game but...i could do anything in the time between turns.
6.) Had a bug that after designing a unit, my sovreign had it's image but on the next turn it was back to normal.
7.) Terraforming..you can make land green but..this really does nothing. hoped for a bit of food production as a benefit. Could be integrated as food production and barren land as food killer to use it on enemy land. Would be practical for cities that don't have the ability to build farms.
8.) Sometimes player points after savegame loading aren't correct but are back to normal after a turn.
