Couple of Bugs

1) Border Bug

everytime i finish the game and i load it again my borders switch. I do not expand in the south of my map, and my cities do not grow, yet after loading my border shrink only to expand it to the previous state after i hit end turn. When my borders shrink i loose all the mines, farms etc. i have build and i have to rebuild them again when my territory come back to normal. Extremely annoying.

2) Teleport Bug.

i can still teleport to a tile occupied by my enemy and nothing happens - we just share the same tile. I have to go out and attack for something to happen.

3) Indestructible pioneer 

I had a case when i could not kill pioneer - actually i killed him several time (both autoresolve and tacktical battles) and he was still there ... Only after saving and loading he disappeared.

4) Groups 

To recruits groups you need both: a war council (building in the city) and technology. It took me long time to figure it out. I build war councils which inform me i can build groups, and yet i couldn't ...

Other bugs - with soldiers resisting archers all the times and wrong numbers of damaged dealt was already pointed out.

I am playing first game, 100 turns or so on ridicuoulous level and i have already 10000 gold, 20 food etc. -> very discouraging to build and take care of your cities since i have all i need. Still way too easy. I do not know how someone can lose a city if you can teleport easily back and  forth ...
